How do I repair my pickup?
Fluctuates rpm going cruise speed (600-1000 rpm), hard
starts, 4 minutes to idle down, 8 minutes to move temp
needle, stalls randomly at idle. Cleaned MAF sensor and
throttle body, replaced transmission (used) and fuel pump.
Scanner detects multiple misfire cylinder 3 and coolant
temperature sensor. 142000 miles. What should I
check/replace?
