Hello I am new to this forum but have been getting info for some time now from here

My problem is after taking my car to the dealer for the cam, can follower , and hpfp my car has a misfire in cylinder 3. The dealer said it was the injector. I replaced the injector, spark plugs, tested the coil, and clean out the carbon from all the cylinders. I have no idea what it could be and I really don't want to take it back to the dealer because everytime I get it back from there something else gets broken... Any Ideas? And my car was running fine before I took it in no check engine light or misfire before...

 

Coil pack? Not terribly expensive to try it and see if it fixes it.

 

Na I already did the coils and spark plugs :/

 

Well, you only said you tested it. Have you tried just resetting the code and see if it comes back? You could also swap stuff to a different cylinder and see if the code moves.

 

Yea I reset it moved plugs and coils around and still get the misfire in the same cylinder

 

Sorry, bud. I'm out then. It's possible the new injector is bad or you have deeper (and more expensive) problems with that cylinder. I'd be taking it in at this point as I don't dig deeper than the "easy" stuff. Sorry!

 

So I took my car to the dealer and there saying that I have to put my car back to stock... Even though I dropped my car off with no codes or cel so I'm just going to park my car untill I can save up some money to take it to a shop...

 

Put your car back to stock? tell us what you've done to it, that might help.
