Went and messed with it some more. After 8 months of this I am about to give up. Everything I do results in it running worse. I think this may be my final post on this. Compression is 150 all, Fuel pressure holds steady at 30lbs. FPR is new and not leaking. There don't seem to be any vacuum leaks and ALL gaskets have been replaced (Except head), Coil seems good. TFI is new. Engine supposedly has 115,000 on it. (got wrecked and sat for a while) IAC is good. MAP seems good. Engine actually runs better if I disconnect the red vacuum line behind the throttle body. O2 sensor hasn't been tested yet but looks new. Will test. Plugged cats maybe? Doesn't really have the typical plugged cat loss of power. Plugs, wires, cap and rotor are all new. Plug gap is .044. New radiator, thermostat, temp gauge sensor and water pump. Have not tested air temp sensor or coolant temp sensor. Switched out the computer.
Maybe I need to let the newer computer "relearn" for a while??
Could there be any fusible links, gas return lines, relays, etc... that I need to go after?
Last call for ideas on this?? Getting close to selling it and I REALLY don't want to do that. Waited over 10 years to have a BII again.
