my idle is at 400-500 and bounce around there, sometimes the idle drops to 0 and comes back to 400-500, i tired tuning the BAC valve and also the MAF? or is that AFM? but i tried tuning the thing by the air filter too with a screw driver, doesn't help. I hanv't gotten a chance to check the TPS though.

One thing that puzzle me when i take out the pressure sensor vacuum hose, the idle is PERFECTLY at 750/800 and does not bounce. So i think i'm going to test the pressure sensor before i do TPS.

also on second gear (havn't gone 3rd/4th/5th yet) when i drive hard to 7k rpm at 5k rpm the boost turns off/weak until 5.5k and suddenly boost kicks back in hard straight to 7k, wussup with that? btw. oringinal owner had fcd and intake, but was taken off.

could all this be that the pressure sensor is tow up?

it's not a "pill" problem either because i have the pill, someone help me out here, i know some people have problems like this, i searched but everyone end up not explaning that they fixed it or not or how they did it.

 

Try adjusting the idle mixture screw.&nbsp Pulling the hose is like inducing a slight intake leak, which shows that you're running a little richer than spec.
