Check engine light pulling out of driveway rough idle engine cold

[Ryguy29]

Have a check engine light that goes away when cleared and warmed up , car has 70k miles . Will pull codes one of these days thinking it might be plugs as the car is tuned and they have over 10k miles on them , coil packs haven’t been replaced yet . Any information or somebody had this problem in this past ? Car is running fine it seems

It’s fuel, air, or spark. Pull the codes and then investigate from there.

Turns out the bolts won’t tighten up enough to make pipes seat nice and tight ? Their evolution charge pipes . Any body have this issue ? Bolt is deff at its limit and has 1/8th to 1/4 of play , almost seems like washer isn’t flat anymore but it’s part of the charge pipe..: might hafta throw the stocks on to see if this is the problem …



Tried taking a video having trouble uploading /if you would like to see one please text if you don’t mind I really would like to figure this out Ryan 516-642-2866

after messing around a little got the stock to fit nice and snug and was determined to get er back on , noticed a bit of oil moving the oring clean that and seems to have seated properly now / this still has some play but not as bad as it was when it gave me a code , was thinking to order a set of mishimoto soon...

Sorry, not familiar with Evo pipes. Maybe someone else on here knows.
