Car continues to misfire. Replaced spark plugs, wires, coils, module, fuel pressure regulator, and injectors. What else is left to do, without spending more money!!!!!!!


Guessing is the way to spend the most amount of money. After spending a lot of money guessing, most people dont want to spend money fixing the real problem, which in all cases, cost less than what they have spent. A shop will need to take it from here, First is to narrow down which cylinder is misfiring then go from there, Check fuel trims, compression, Vac leak, signal from the injector to the ecm. The injector is hot and the ecm grounds it. You dont say which engine you have, but the 2.4L have had a lot of coil housings go bad.

You can still drive it with the engine light on. It may not run too well or you may not notice any difference at all. If the light flashes on and off while driving then you shouldn't drive it because damage to the catalytic converter may be a result. I hope this helps.

Hi.I have a 1998 Dodge Avenger sport with almost 53,000 miles on it.Car is automatic with V6 and 2.5L.The check engine light stays on.I took car to sears auto center and was told the computer in the car is shot.I need a new computer.That is why the check engine light stays on.I was also told that new computer will cost alot of money.The car runs perfect.No problems with it.The car will not pass state inspection with this issue.What should I do now?? I don't have alot of money to spend.Can someone please help me out?? Thanks.


I really hate to say this because i don't recommend used parts to be put into a vehicle especially when it comes to electrical or computer components, but you may be able to check your local parts yards and see if they may have what you need if you are on a tight budget. Or you may have to buy a new computer. I would have also take it somewhere else for a second opinion before spending the money on a new computer. ope this helps.
