89 stock w-e303 runnin rich-bad
check engine light seems to go out when the power is there,otherwise it will backfire thru the intake and all kinds of hell.o2 sensors are new.only 20k on the new motor.e303 are only deviations from stock.seems to be worse in warmer weather.i have figured MAF,EGR,fuel regulator or just a bad computer.fuel pressure reads within specs at idle.PLEASE help.
