Question about 1994 Ford F150 Styleside Supercab
TRUCK BUCKS UNDER LOAD NEW PLUGS CAP ROTOR GOOD COIL
I had a similar problem with my 1999 E150 Van. After changing plugs and wires didn't solve the problem, my service technician said it was a problem with the automatic transmission. That was hooey! (technical term :-) In my case, the service engine light came on. I don't remember the exact codes, but they pointed me to 2 problems. 1) Misfire on #4. 2) O2 sensor error.
I researched the O2 sensor problem and found out that it was probably caused by a dirty Max Air Flow (MAF) sensor. On my van, the sensor is accessible by taking out the air filter. It's a very fine wire just beyond the filter. Spraying the MAF sensor with some electrical contact cleaner solved the bucking problem. (CRC brand electrical contact cleaner available at Wal-Mart for about 3 bucks)
Hope this helps.
