Engine Performance problem
1998 Ford F150 6 cyl Two Wheel Drive Manual 160000 miles
This is my Dad's truck. It started running rough a couple weeks ago and has gotten worse. Replaced inline fuel filter, no help. Replaced both front OS2 sensors, no help. Mechanic tested catalytic converter and said that is not the problem. When you start out in 1st gear you can just barely push the gas pedal or it will bog down to nothing. Once into 4th gear it seems to run OK as long as it's a straightaway, if you hit a hill all power is lost. You get nothing when you give it gas. If you rev the engine in park it backfires. Any help is appreciated becuase he won't take it to the shop and I'm left trying to figure it out. He changed the plugs about 2 months ago.
have the same problem?
