2002 Ford Explorer Sport Trac Q&A

2002 Ford Explorer Sport Trac Question: changed the heater control valve, now the oil gauge goes crazy why?

ruff idle and the code says # 2 misfire and the oil pressure gauge jumps back and forth to high and low when you put it in drive and reverse... what would be the cause? -
Answer 1
