I finally got the engine in my car and I'm having high/ hanging idle issues. Its a 99 gt with 2.1 KB, 36lb injectors, 75mm tb, 90mm maf, 255lph fuel pump with KB boost a pump, manual transmission, doesn't have cats and I have the mil eliminator a for the rear o2s. I cant find a vacuum leak anywhere. New iac and pcv. I hooked the scanner up to it and here are some of the readings I wrote down: IAC DUTY CYCLE=48% MAF=9.5-9.98(GM/S)1.06-1.1volts IAT=143Â°F, 1.14volts ECT=192Â°F O2s11=932mv O2s21=964mv One menu said the fuel rail pressure was 37.6psi and another said it was 57psi What do you think?
