Hi Guys,
I have an 88 mustang 5.0, T5, GT40P heads, andys springs, e303 cam, typhoon intake, 70mm BBK throttle body, EGR has all been deleted, long tube headers, 24# injectors, C&L mass air with blue sample tube, Powerdyne BD11A blower, C3W1 computer..
My issue is this, the engine was built by me, this year, its all brand new from pan to intake. Since assembly I have not driven the car, I have started it but I cant get it to idle. It surges badly. It also runs so rich it burns your eyes.I have verified no vacuum leaks (12-15 inches vacuum), set the TPS voltage to .95 at idle, I did grind a small channel into the AIC between the ports as I read the e303 is too much lump and the IAC cant compensate fast enough. I read that would fix the surge, it didnt. I set the idle with the IAC disconnected and the spout out of the distributor, and it will idle around 600, but eventually stall or start surging.
My KOEO codes are 81 and 82 (emissions control). Im ok with that. However,
My KOER coes are 21, 41, 91, 33.
21- coolant temp out of range, may be part of why so rich
41- o2 sensor signal
91- Oxygen sensor problem, fuel pressure out of specified range or injectors out of balance
33- Canister or EGR valve not operating properly
33 isnt so concerning right now, but 41 and 91 are. I did read somewhere about having to repin the o2 harness? I believe my 88 is a late 88 and it does have the extra loop wire. Should that be pinned from 1-6 for auto? Have I toasted my auto ecm or can it be repinned to work correctly? Is this even my problem or am I looking in the wrong area. The orange ground wire is grounded to bellhousing bolt, not the head, but that should be a good ground.
I guess my question is, will my stock 88 t5 harness work with the C3W1 auto ecm ?
Thanks for taking the time to read and any input you have on my problem. Id like to get it running right so it can go to the body shop this winter.
