no year car told, gee hope it is not 89 to 90 year, 91-95 is better, is it?
now lets do RICH AFR fueling rates bad.
testing 1 2, 3.
Does water (coolant ) temps hold steady at 180f ? if not thermostat is bad or wrong gasket used. 92 up uses rubber ring and not paper gaskets.
ECT reads 300 ohm hot engine? or at idle (0.7vdc) ? this means 180F, that voltage. does it?
fuel pressure at spec, at idle and 3000 RPM ., 34-41PSI at sea level , does it? stock car has test port on end of fuel filter banjo bolt 6mm ISO thread.
look for injector leaking at key OFF CUT ? eyes on it, air horn pulled , this engine has no mAF so air horn off EFI runs perfectly.
run better o2 sensor pulled plug? they can fail and force rich FOR SURE STUCK AT 0vdc, hard. most bad 02 stick low by design, failed (makers rules)
ever reCAP the ECU. most need this if never done ONCE.
map sensor tests pass>
