My check engine light has periodically come on and off. Usually it is after filing with gas. Yesturday my Check Engine Light came on and will now not stop blinking. The car is bucking and it feels like there is no pick up upon acceleration at all. This morning it almost felt like the car was going to stall, but it didnt. Can you help me to let me know what it might be? How expensive, and can I run the car in this condition right now?
Thank you kindly.

I think you need to replace your Intake manifold and air sensor. Parts are less than $100 combined. Very easy to do yourself.
Good luck

My problem was a split vacuum hose. There are 3 which basically sit on top of the engine.

Alright so at 1093 miles, the Check Engine light has finally returned. I guess I will bring it in to get it checked out.

A month ago I had my car inspected. When I got it back from the dealership that evening my check engine light came on. Since it was Friday, I had to wait until Monday to call. The car's performance seemed fine over the weekend. Monday morning I filled the car up with gasoline at the local Getty in town, then called the dealership. They first asked if I didn't tighten the gas cap-to which I replied the problem began Friday evening, I did not put any fuel into the car until that morning. They advised to bring it in. Later they called to advise the problem was my catalytic onverter and I would need to have it replaced, they would need to order one as it isn't a stock item. I told them I would wait until I had enough money for the repair. The check engine light stayed on until I refilled the tank at a Cumberland Farms station using the mid grade gas, then it went off within 10 miles of refueling. I noticed the light stays off as long as the fuel doesn't get below a quarter tank. Then this week I filled again at the Getty station and my Check Engine light came back on and stayed on until I refueld-I allowed the gas to run down to nearly empty then filled at Hess using the mid grade fuel. Again, within 10 miles of topping off my tank the light went out again. Is there really a problem with my catalytic converter or is it a problem associated with the fuel grade which triggers a sensor? Please advise. Thank you, Erica

Fuel grade wont trigger the issue. Hard to say if your catalytic convertor is bad or not. But it dont sound like that is causing your problem.

Best bet would be to get to a autozone and have them scan the code when the light is on and see what it throws. And post them back to me.

Or if you have a copy of the repair order estimate from the dealership they might have a copy of the code on it.

I have been having problems with my car the check engine light is blinking. It woudnt turn over I got a friend to jump start it started but he took it for a run around the block and the check engne light is blinking. I have no idea what this means my friend said is could just be a sensor but he doesnt know cars well.

Figured I would see if you would have advice before I took it in to a shop and got billed out my bottom for something simple.

Thank you in advance

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

1999 Mazda Protege 5spd. 125,000 KMs Engine light has come on and stayed. Replaced the EGR Valve. Light went out. Week later, came on and stayed. Drove it this way for a couple weeks, then tonight, started real rough and light started flashing. Light flashed all the way to the mechanics'. Any ideas what causes the flashing light, and how serious this would be? Thanks!

Well.

How good is your mechanic? Why was yor EGR valve replaced? EGR valve are common on those engines. But so are ignition coils. Ahev him check hte coil and wires to see if they are firing properly and find out what the code is before you reply to this

Have it scan and comeback with the code or codes, if its an EGR problem it will fall between these codes P0400-P0408.

Try this tap the EGR while its running rough, if its smooths out, you've found your problem-if not open it up and check thoroughly for excess carbon at the pintle, intake and exhaust manifold sides. If all these checks out, then we'll go somewhere else, this is just the start. But we still need the codes-take it to autozone its free, just be nice to the partmans that way you wont have to buy something.

Daughter took her car to dealer. They diagnosed and found error codes PO171 and PO420. It is running good with no problem other than the light. Last year it was the gas cap.

They are suggesting replacing the O2 sensor, coil, wriing, plugs and even the cat. Converter. $2000 woth of work. She is on a budget- what could the problem be and what would be the least costly way to solve the problem. If she does nothing for a few weeks what could result?

Thanks

P0171 and the p0420 codes could be related due to bad sensors or they could be related due to the coil and previous things listed by the part place.

Id change the o2 sensors first and see how it goes.

The only thing that will happen is poor gas mileage and poor engine performance.
