hey, I just have a quick question. I got a 98 camaro 3.8L. Cylinder #1 is missfiring ( at least that is what the diagnostic at autozone told me). I have replaced all my coils. spark plugs, and wires. What else do you think it could be?? So I don't waste all my $$$. Thanks.

 

I had this a similar problem like this in my 98. I went up to autozone to have it tested and it read one of my cylinders was misfiring. I took it to a place to have it fixed and they said it was my fuel injectors. Both of these were wrong. It turned out that a little rubber hose next to the fire wall ( real pain to get to) was leaking gas into the cylinder. When this was happening my car's idle would jump up and down severly. If yours is doing this ask somebody about it. Hope this helps.

 

could it be the distributer? Try ajusting the timing. Very simple and sometimes the correct thing to do. Give it a try with a timing light. Have fun

 

mine did the same thing, and we took it in they replaced the head coils, and pressure cleaned all the injectors, costing like 500 bucks, later on did we find out it was the pressure control valve, only 50 bucks. so yeah, that fixed it, maybe this will help ya
