Hey Ryan how have thing beengoing? We have tested this one and we found B20b will run fine on a P75 do to the very low cr. Just dont run 87-88oct in it. Now the B20z does run lean on a P75.

Everything has been going OK. Probably something to do with the IACV or a vacuum leak somewhere then. When he had his Si ECU in the car, it would idle high until the engine light came on then it would go out. Should be pretty easy to track down the problem now that a more correct ECU is in there.

ok i did what you said and plug a hole at a time and when i plugged the top one it liked to suck my finger in and the idle dropped so what is the problem you think

if its the the hole on the upper part of the throttle body then it sounds like your IACV. clean that out. its probably clogged.

that would be the FIT valve not the IAC valve.. The FIT valve is located on the underside of the throttle body. mostly found on obd1's. the IAC valve is located on the back of the intake manifold plenum.

ok tonight put a new gasket on and the idle went from 2000 to 1000 which was good but when i let the car set in idle for a while it will drop so low it dies so now the idle is to low i adjust the idle and it does nothing it sucks harder but stays at like 100 rpms
