Throttle Body Problem
I posted my issue a few days ago...I'm adding updated info and continue my quest for the answer.
2004 Ford F150 5.4L 8cyl., Has been having problems accelerating over 30mph especially with OD on. OD off seems to run just OK. Has stalled a few times when coming to a stop after long driving...started right back up. Took it to the dealer and got codes P0104, P0121, P0221, P2104 and P2111. They wanted to replace the Throttle body and MAF sensor for $1000, changed them out myself for about $300, but the problem persists. I disconnected the battery also for a few minutes to try and reset everything. Truck is still running ****ty...any ideas?
