- 2001 Ford Sport Trac
I have 155,000 miles on my 2001 Gen 2 sport trac. I think my plugs and wires were original. I changed the Autolite Double Platinum (APP103) with Motorcraft SP-500 Fine Wall Platinum and new Motorcraft WR5944 Spark plug wires. The old plugs had gaps ranging from .051” to .072”. I did not mark where they came from. I did not gap the new plugs because I was afraid to damage the new smaller electrode. My hi-way millage went from 18MPG to 20 MPG and around town increased. I can feel more power from the engine. Probably getting about 50 more miles per tank.
Right bank was a PIA with a hard line in the way and the heater core there. Did the right entirely from the wheel well. Left bank can be done from the top. Much easier. All plugs were tight coming out. I was sure I would have to run a tap dome the threads, but I did not have too. Put anti seize on the plugs and Di-Electric grease on the new plug wires. Took about 3 hours, took my time.
I cleaned the Throttle body, the IAC valve, and replaced the PCV valve with a new plastic line and elbow.
I want to thank everyone in the group that posted on these subjects. I read many post and reviewed some pictures. Can’t remember who they were, But thanks a bunch.
