Default Re: Ford vs Chevy Build-up

Yep,

I agree with Dave...Looks like Intake Air Temp is way off at -30 .....that will make it way rich. Usually default is -40 when they are unhooked but check for the open plug. IAT sensor looks like your coolant sensor except the end is not sealed with brass, it has a thermistor exposed to get air temp. Should be screwed into #5 intake port or you can move it into the intake upper plenum by using one of the plugs located on the underside of the intake. O2s are not used in the base calculations for fuel..they are more like trimmers when the system is warm and in closed loop so they are not players on initial starts. I'm curious about the -29HG ..is that the.baro reading? Usually that is just expressed as a positive #

Basics to get it running TP, ECT, IAT, BARO, Fuel Pressure, base timing. Looks like you are getting closer!
