Engine Performance problem
1997 Ford Explorer 4 cyl Two Wheel Drive Automatic
I have a pushrod 4 cyl 97 Ford Explorer with 154,000 miles. It's got a rough idle and very sluggish acceleration. Replaced plugs and wires after I got a P0171 code on it, then drove it for a week and still got the same performance. Just got the P0171 code with the same misfires - 1,3, and 6. Air filter's clean, no buildup in the intake manifold, no vacuum leaks that I can tell. Should I replace the coil? Any other ideas?
