OH, OK .......Now I get it
I installed this kid today on my Hybrid CJ5 / '84 Turbo 231 . After getting to closed loop warm engine idle , when I shut her down & start her back up, It stays at Rich for about thirty seconds. Then it will operate as it should ....beside's reading the O2 sensor , would this also be a function of the IAC . She does hunt up & down a bit @ warm idle ?
