5.0 no idle cold and backfires. PLEAE HELP!
Ok guys I am fighting the same monster here. It wont idle at cod start have to start 4 or 5 times and keep working the throttle to get it to run. Once it does idle when I pop the throttle it backfires, and I can hear a slight miss. car runs rich as hell (eye watering rich) codes are all air bypass etc. thats all removed. I have put wires cap rotor. Cut out the ten pins and wired them straight. New TPS swapped in a good IAC. short ram air intake 2040 compucam and new o2 sensors. GUYS PLEASE ANY HELP IDEAS would be appreciated. computer maybe that my next idea.
