View Full Version : SR20 Sputtering

07-24-2008, 08:14 PM
My redtop is sputtering pretty badly around the same time my boost spools up ( around 4000 rpms.) It's getting worse. I'm hoping its just the spark plugs. I just bought some today and they'll be in tomorrow. If not any ideas what else it could be? It bogs and sputters really bad. Oh and a friend suggested the CAS, if that's the case any ideas how much they run?

nope, im 98.9% positive its a leak in the intercooler piping.

Check all clamps and hoses.

wow this forum rocks, thanks alot!! Hopefully its just my fmic. That's very possible too because I recently got ran off the road and blew out my front bumper. So there's a good chance it could have messed up my fmic, hopefully it a clamp just came lose or something. I think I might be using this forum from now on.

well I don't think it's the intercooler. All the clamps and hoses seem to look pretty good. I accidently got NGK 6's today, but I ordered 7 iridiums that I'm picking up tomorrow, but I;m still gonna throw the 6's in tonight and see if it helps and like 10-12 lbs of boost.
