If you can, get me the codes that are in the PCM and i can go from there.
Thanks!
I was getting a code stating cyl. 1 misfire. Plugs, wires, then coilpack didn't fix that like I thought it would. Next a shop replaced all the injectors and told me the reason it wasn't running any better was it needed catalytic converters replaced. It won't run at any speed without missing, but right now there are no codes. I do hear something that sounds like a vacuum leak, but can't locate it.
Shouldn't it throw a code if there is a vacuum leak?
