[s-cars] Rough idle?

[Alvin Labonite]

I did notice the brown ring on the plugs. What do you mean by blow thru? I
have the OEM plugs that does not require gapping.

I have samcoes all around and metal cross over pipes and metal end tank on
OEM intercooler.

Check MAF to turbo hose too and no cracks..

I thought about plugs.

Thanks.
