Hi guys i,m new to the forum but i have a 2007 sebring 2.4lt that is misfiring and engine light coming on. i had the chrysler dealer plug in the computer and tell me that the coils had failed so i replaced the coils and was ok for 2 days now has started misfiring again and engine light is back on. is there something else we are not seeing here? can anyone help.?
Thanks in advance

 

Whenever the check engine light comes on, it means that the computer has detected a problem and has turned it on. There will always be a stored fault code any time the light is on. Since you just had it in to the dealer for essentially the same complaint, you should take it back there and they should, at the very least, look at it and tell you what is going wrong. They definitely owe you at least that. If they give you the run-around, you should insist that you have already paid them for a diagnosis and repair and that you expect them to deliver exactly that. They have failed to do so thus far.
Without a chance to look at the car and hook it up to a code reader, nobody here can tell you what is wrong with the car. You might consider taking it to a local AutoZone where they will read the error codes for free (except in California) before you go back to the dealer.
By the way, it's pretty unlikely that all four coils will fail at the same time. Coil failure is pretty rare anyway since there are no moving parts in an ignition coil, and four failing at once sounds absurd. A more likely cause of an engine miss would be spark plugs. Always replace the cheapest parts first if you are not sure of the cause of a problem.

 

Plugs are near new and if there fouled up they would run bad all the time. Dealer says coils go bad on this model a lot. Just thought maybe some one on the forum may have had a similar issue.

 

Ended up being crank position sensor. Chrysler dealer over here misdiagnosed I purchased a generic each reader from eBay for $200 and fixed myself. Thanks chrysler

 

Fine job. That code reader can pay for itself after only a few uses.

 

Especially with the amount chrysler charge and to diagnose it incorrect would have cost me even more if I took it back
