Well i got a CEL yesterday and the code was PO300. Engine Misifre Detected-PCM. anyone know what this could be?

 

check your plugs...

 

is a random misfire code. Best way to check is with an engine analyzer or to do a cylinder balance test. Prob fouled plugs or something

 

I got that code along with my car being noticeably slower . It ended up being my plugs , even though they physically appeared to be healthy plugs , when I took them out . Put new plugs , got my power back and havent thrown that code since .

 

yeah ive got a loss of power. i thought it was the Cat

 

Change ur plugs , itll make ya smile I jus put stocker NGK's back in till I up the boost .

 

I had the PO301 Missfire on cylinder #1 code and P0107 Lean on bank one code over the weekend and my car would barely stay running. I just got it back from the dealer yesterday and they replaced the plugs coils and injectors. They said it was most likely the injectors, but they used the shotgun approach just to be safe.
