Re: 1997 Ford E150 Van V6 Runs Rough, Misses under load
Tried the cleaning of the MAF sensor with official cleaner 3 times now.
I have changed out the following parts
1) Spark plugs (last year) - Autolite... not the Bosch problem plugs
2) Coil - friends say this solved many of their problems inthe past
3) Plug wires
4) EGR valve - worth a shot
5) Cleaned the MAF sensor - with approved cleaner
6) Fuel Filter - 5 month ago
7) Checked for vacuum leaks
Today, due to interstate driving, I got a new set of codes:
P0122 TPS Predal Position Sensor A - Low input
P0302 Cyl 2 Misfire
P0123 TPS Pedal Positin sensor- High Input
P1121 Manual control fuel/Air Metering
P0171 System Lean Bank 1 (Left)
I changed the TPS sensor. Changed spark plugs again with Champion Copper instead of Autolite Platinums. 2 year old Platinums had carbon buildup.
No improvement. Still runs rough under any load. does maybe ok sometimes, but low on power and shakes hard most of the time.
I am about to change the MAF sensor. Otherwise, I am starting to think cylider compression or injector.
any further thoughts?
