Welcome to FTE.
I dont wanna sound like a jerk, but if youve been reading for 4 months, I msure you know the first thing you should have done is to run an EEC self test, what codes do you have? post up your codes and lets go from there.

I've been having this problem since the last subzero temp period. When starting cold, I've had extremely rich conditions. Engine lopes bad when warming up. I replaced; Heated Oxegen Sensor, Fuel filter, spark plugs, air filter, IAC, MAP. I've cleaned the throttle body, cleaned and tested EGR, tested ECT, IAT, EVP. I am still getting a rich lopeing condition at cold startup and it takes it much longer to warm than it used to. I got me a code reader and checked codes; KOEO I got (11) system passed, In memory I got (33) EGR fault/ not closing (34) EVAP control fault, (41) No HEGO switching detected. next ran KOER test, results; (42) HEGO sensor voltage high/ system rich, (18) Spout circuit open - Spark Angle Word (SAW) failure.
All I can think is to test the HEGO, but my Chilton book says how to check, but tells me the voltage values are on a table that is not there! I also have a miniscule coolant leak that I can not locate.
anyone help this poorboy out?
