Can some one help me, I have buddy club 272/272 everything ran prefect(tune), I stall my stock for smoke and everything was fine, 8 hr later I install my buddy club back in and now it stalls out every other red light..

 

Smog*

 

Car won't even idle w ac on

 

My idle is fine when I'm sitting still, but when I'm rolling 30+mph , and put it in neutral my rpms raise to 1500 then drop to 1000, and does this over, and over untill I stop.

I am leaking at the tb shaft seal, and have quite a bit of air coming through the breather hose also. I cleaned, and checked my pcv valve seems to be doing its job. I'm stumped as of right now. Help me out

I have gsc s2's AMS tune, and it been great until I recently boost leak test, now its all messed up. Ordered a new TB, but the shaft seals have always leaked. Maybe it got worse when I pressure checked this last time. I'm all out of ideas.

 

Maybe it's like what I had??

FYI - This is definately *not* advanced

 

Get a Tune-- but you can also try and reset your ecu by disconnecting the battery and letting it sit for a few minutes---this might smooth it out a little bit once it relearns the new perameters--doesnt take place of a tune though.

 

Your idle may be off untill you bump the RPM up or get the tune done properly.

 

Thanks I will give this a try along with the new tb.

I know this isn't "advanced",but it was the only thread I found that described my symptoms.

The car is tuned by ams, and its been great just recently started doing this out of nowhere.

Thought it had something to do with my pcv since boost leak test had a lot of air coming though the breather hose.

 

you can't say 272's are big cams in general. it depends on the manufacture, each 272 cams has different specs, 272 is just an advertising duration. for ex. HKS 272 VS KELFORD 272 are two totally different cams, HKS one is very mild cams compare to kelfords
