I have a 2006 Dodge Stratus 4 cyl. The check engine light came on and it came up 4th cylinder misfire. The check engine light now flashes when I am driving through the city but not on the highway or freeway. A mechanic told me that it needed a new exhaust valve, does that sound right?

Need to find out the reason first.

Codes never identify bad parts, just failed systems.

Start witha compression test. Check plugs, coil/wires as well.

My gas guage said I had 1/8 it started missing and shut off, I put gas in and after cranking for a while it started. Then today it said I had just under a half a tank and did the same thing. I thought it could be the sending unit although I am not sure how much gas it actually used. If I change the sending unit how can I be sure that was it? Could it be something else that would cause it to shut if it doesnt have a certain amount of gas in it like the fuel pump, and if so why would the amount change?

What to do is fill the tank and set the trip odometer. You should get nearly 300 miles + from a tank of fuel. Run it until it gets near 300 miles and see what the fuel gauge says and then check how many gallons of fuel the tank takes to refill. I believe you have a 16 gallon tank.

Let me know what you find.

I did what you said and determined that the guage is off by about 1/4 of a tank. So now is it the guage itself or something else like the sending unit?

Thanks

Chances are it is the sending unit from the tank. The only way to be 100% sure is to remove it and check voltage drop as the float drops. I wish I had an easier answer for you.

Let me know if you have other questions.

Car misfires and shakes badly at 2750 rpms. I replaced all spark plugs. I also replaced the coil and fuel injector for #2. Still misfire on #2. I get codes p0202 and p0302. Compression test was done and it was good. Can it be the injector connector and how do I check it? I need to take intake manifold to get to injectors.

I have a 4 door 2005 Dodge Stratus and I turned on the interstate this morning when it started to skip violently. I couldn't accelerate over 55 mph or 2.5 rpm and it lasted for awhile. I got it back to someone I know who knows a little bit about cars to show him and it ran fine. The engine light is on. Any help please?

Once the Check Engine light turned on, there is a diagnostic fault code stored in the Engine Computer's memory. Many auto parts stores will read those codes for you for free. That will get you into the right circuit or system with the problem, not necessarily the specific defective part.

I'd still visually check for spark at the plugs. Check for injector pulse, also, use a noid lite.

How do you check the electrical connector to the injector? You have to take the intake manifold off or can you do that without removing it and how do you do it?

When the car gets heated up or it is really hot outside the car starts to chug and sputter then dies. The check engine light came on. And the car will not start until it is cooled down outside and the car is cooled off.

Check engine light:

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis, finding out what's going on.

I have an intermittent misfire at idle & intermittent hesitation. New plugs 5000 miles ago. Seems to be worse the warmer the ambient temperature - engine temp seems to have no bearing on miss. No check engine light.

Misfires can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.
