Alright, first off I have a wiring specialties harness so I assume all wiring is good to go. all connections are secured well.
Got the car running a couple days ago but it was stumbling and dying easily and I could barely get into boost it's missing out so bad.
I have a Greddy knockoff intake manifold and the teflon gasket that came with it was leaking, as there was fuel on top of the gasket.
Replaced that with the stock IM gasket, no more fuel leaking there, assume its good to go.
The car is still missing at idle really bad, I've checked everything for leaks with soapy water and can't find anything. I can rev it up to about 5500-6k if I barely push the throttle down a little as I go but then it starts breaking up and missing.
Driving it pulls pretty well with little to no miss from 2k rpms to about 3300 and then it breaks up bad up to around 4k and it just refuses to go any higher no matter how much or little throttle.
I've changed MAFs with a known good one, I changed the coils with no effect, I've gapped my plugs to .027"-.028", if I unplug the MAF it idles the same but wont rev over the 2500 limit... When I first cold started it this morning I unplugged the coolant temp sensor and it seemed to run a little better until it warmed up and then it died and wouldnt start again until I plugged it back in.
Also I set my CAS exactly how the FSM says to, lined the right most dot up, slid the CAS in and then it lined up with the left most dot perfectly.
I pulled my plugs out and replaced them with the ones that came in the engine and nothing changed, though my plugs were really black so I cleaned them off before putting them back in (when I gapped them) with no change.
I can't think of anything else right now that I've tried but since Saturday I've done nothing but search and troubleshoot with no increase in performance to speak of. Can anyone help me!?
