So driving home check engine light and message to service stablitrak and traction control came on.
I took it to the dealership and upon diagnostic the guy told me it was my ignition coil and spark plugs because of the code P0304 cylinder four misfiring.
I purchased new coil and plugs and replace the old one. Since I did not have an OBD scanner I disconnected the battery terminals to reset the codes. After I took my car for a test drive but the stablitrak symbol came on again.
This time engine check light stayed off.
I can feel the car still driving a little jerky and reduced power on the engine.
I do not know what is going on.

Please help I would really appreciate it.

Hi and thanks for using 2CarPros.

The stability traction control really had nothing to do with the misfire. Chances are there is a bad wheel speed sensor which is causing the light. I am surprised that he did not give you the diagnostic trouble codes related to that light being on. Chances are there is a bad wheel speed sensor.

What I suggest is this. Have the person with the scanner read the codes again. Since the light is on (even though the engine light is off) there will be codes related to the stability traction control system.

Since you repaired the p0304 problem, the check engine light should not come on. However, since you disconnected the battery, the vehicle may have to relearn everything and it should start smoothing out the engine as it relearns.

If you can, get the code for the stability traction control and I will be able to direct you.

Take care,
Joe

Yes, I went to the dealership today and it was just the stablitrak light and when he hooked the diagnostic tool it was p0304 which is for cylinder misfire, but I already replaced spark plugs and ignition coil and made sure that the coil spring is seated concentric so it can make proper contact with the plug. He cleared the codes and told me to drive around and see if the code came back on. As soon as it came back on I went back again and same P0304 code and mentioned that need to do a detailed diagnostic for which they charge an arm and a leg and I cannot afford dealership costs.

Hi again:

Is it the P0304 again? That is an engine code. If the engine misfire was bad enough to really jolt the vehicle, then the stability control may need to be reprogrammed. However, a misfire itself is not turning the trac control light on.

I took apart the engine again to make sure everything was done properly for the second time and I checked all the spark plugs and ignition coil. Everything looks okay physically but I hooked up an OBD scanner to the car again now and it show P0304 three times, first one says
1. P0304 (1/3 something)
2. P0304 (2/3 Stored)
3. P0304 (3/3 permanent)

All of these correspond to cylinder four misfiring but it has brand new everything.

So I do not know what to do now other than taking it to the dealership. :(

Okay, we have to keep in mind, a misfire can be caused by more things than a coil or plug. Here is what I want you to do. Clear the codes. Disconnect the negative battery terminal while you do the following.

Remove the coil pack and plug and inspect the plug's condition and let me know what it looks like, black, wet.

If it looks normal, switch the plug and coil with cylinder one plug and coil.

Reconnect the battery and start the engine. If the light comes on again, check to see if the misfire moved to cylinder one (P0301). If it did, then we have a problem with either the coil or the plug. If it does not change, then we need to start checking fuel pressure, injectors.

Ultimately, with this many miles, it could be a compression issue, timing.

Lets hope for the easiest solution.

Let me know what you find.

I did as instructed and even with the brand new spark plug that I put in cylinder four upon switching it around with the other three brand new spark plugs from the other three cylinders it still show the same code. Sometimes it switches from p0304 to p0300 but nothing else has changed. Same with the coil since that is new as well. Upon clearing the code multiple is and even when I took everything apart the plug from cylinder four looks black and when I look into the engine where spark plug is installed it looks black and shiny and also looks wet. So are you able to help me proceed further in troubleshooting?

I took it to the dealership and they did a compression test and the results were that cylinder four is holding 65 psi which should be 175+. So the guy there told me cylinder four is dead. And further pin pointing the problem they would have to take it apart. I am not sure what went wrong. I maintained my car regularly with the recommended service and everything. Please help.

Hi again.

That is why the plug was wet. It could not fire. Honestly, my first guess is it has something to do with a valve in the head. If they try a wet compression test on that cylinder and compression goes up, then suspect rings.

It has a lot of miles on it, so it may have a burnt valve or ring issue.

Like a day of two ago it was having some issues starting so I jumped it, but couple days later today I tried to start it and there was no juice. I even tried jump starting it after letting it charge but it no lights come on or nothing starts. So I can't even get it to turn on now. Is there any safety parameters that kicked in or something?

Hi again:

If there are now blown fuses, did you check to see if there is power to the fuse box? If there isn't, then you need to check the main fuses in the battery fuse box located near the left strut tower under the hood. If there is no power, confirm fuses 5 and 6 are good. See the attached schematic.

Let me know if it helps.

I replaced the battery from a friends car who also drives a Cruze and my car started no problem. So I figured maybe my battery is gone. Went ahead and got a new battery and the car starts no problem. However, the issue of cylinder four being dead since it was at 65 psi when I got it diagnosed at the dealership. How can I confirm what exactly is wrong inside cylinder four so I can estimate repair costs?

Welcome back:

First, I would start by checking the compression myself to determine it they are correct. If they are, then you need to do what is called a wet compression test. Basically, about a tablespoon of oil into the cylinder to see if the compression increases. If it does, then the problem is the rings. If there is no change, the problem is either a cylinder head gasket a timing issue, or a problem with the valves. Lets start with checking compression both wet and dry. Here are the directions in general showing how to check:

https://www.2carpros.com/articles/how-to-test-engine-compression

Here are the directions specific to your vehicle:

Engine Compression Test
Vehicle Powertrain Management Tune-up and Engine Performance Checks Compression Check Testing and Inspection Component Tests and General Diagnostics Engine Compression Test
ENGINE COMPRESSION TEST
Engine Compression Test

Special Tools

EN-48248 - Cylinder Compression Pressure Gauge

For equivalent regional tools, refer to Special Tools See: Engine > Electrical / Mechanical Repair > Special Tools.

Removal Procedure

1. Remove the throttle body assembly. Refer to Throttle Body Assembly Replacement See: Throttle Body > Removal and Replacement > Throttle Body Assembly Replacement.

2. Remove the spark plugs. Refer to Spark Plug Replacement See: Spark Plug > Removal and Replacement > Spark Plug Replacement.

3. Remove the relay holder cover.

4. Remove the fuel pump relay.

Note: The engine cranking time for the compression test should be less then 10 seconds and at 30 second intervals.

5. Crank the engine with the starter motor for 5 seconds to remove any foreign substances from the cylinders.

6. Prior to taking a compression reading, verify the cranking speed is greater than 300 RPM. If the cranking speed is below 300 RPM, repair the slow cranking speed condition before continuing with the compression test.

7. Install EN-48248 - gauge in the spark plug bore for the cylinder that is being checked.

8. Using the vehicle's starter motor, rotate or crank the engine for 4 compression strokes, puffs, for the cylinder being tested.

9. Observe the compression gauge and note the reading as the compression test is being performed. A normal cylinder reading will be indicated if compression builds up quickly and evenly to the specified level. An abnormal reading will be indicated if compression is low on the first compression stroke, starts increasing on the following compression strokes but does not reach the specified level.

10. Record the compression reading for the cylinder just tested.

11. Repeat steps for all remaining cylinders. All 4 cylinders must be tested to obtain valid test results. Record the readings.

12. The maximum pressure differential should not exceed 100 kPa (14.5 psi).

13. The nominal cylinder compression value is

* for natural aspirated engines 1300 kPa - 1500 kPa (188.5 psi - 217.6 psi).

* for turbo engines 1200 kPa - 1400 kPa (174 psi - 203.1 psi).

Installation Procedure

1. Install the fuel pump relay.

2. Install the relay holder cover.

3. Install the spark plugs. Refer to Spark Plug Replacement See: Spark Plug > Removal and Replacement > Spark Plug Replacement.

4. Install the throttle body assembly. Refer to Throttle Body Assembly Replacement See: Throttle Body > Removal and Replacement > Throttle Body Assembly Replacement.

_______________________________________________
Now, if you find compression low in cylinder 4, add about a tablespoon full of motor oil into cylinder 4 through the spark plug hole. If compression increases, then the problem is related to the piston rings. If it doesn't, then we have to check for a possible blown head gasket. Here is a link that shows how that is done:

https://www.2carpros.com/articles/head-gasket-blown-test

If you find the head gasket isn't an issue, then the cylinder head needs removed so you can inspect the valves for damage. Here are the directions for cylinder head replacement. They are very extensive. Don't even consider this until you have done the aforementioned tests. Also, once you do the tests, I will be better able to give you an idea as to what it may cost to fix.
