ok, after sitting all fall and winter broken its back running
and running badly, it'll stall with the IAC unplugged, and idle is not in a good range. about 600-900 and bouncing
i have to give it some throttle to start the KOER tests
all vac lines look ok, replaced or inspected
i'll start from the beginning just in case it helps
KOEO dumped codes 91 and 96
KOER dumped 12,21, and 91
i COULD NOT run a cylinder balance test...it just wouldnt stay running
FP from my rail guage seems high with the stock reg, very bouncy with vac on, 38-45-ish
and pretty much 45 with vac off
so... i replaced the battery, ECT, i checked the o2 sensors and cleaned connections, i checked the IAC voltages, tps, and ...think thats it
reset the computer..... drove about 20 miles mixed road and hiway
new codes now
cylinder balance test worked...got a 9 (still bouncy idle but no popping etc)
KOEO = 11 only
KOER = 12,94,44 (the smog system is removed)
**EDIT** i should add that the Y pipe is removed, thermactor plugs inserted in heads, and the pipe from the pump to H pipe is closed and cut, all vac lines capped or removed
will the 94,44 codes cause an issue ???? on 6 stangs this is the first one that i had drivability issues with
and why cant i get it to idle correctly, what am i missing ???
