Power and Idling Issues
I have 2004 5.4 Triton Automatic 8cyl.
I know nothing about vehicles so please bear with me. This is actually my husbands truck and it has been running really ****ty for a few months. Mostly it lacks power when going over 40 mph (almost seems to slip into neutral), idles a bit rough, has stalled a few times when coming to a stop. My husband took it to the dealer and got back a few codes: P0104, P0121, P0221, P2104, P2111. They want to change out the Throttle and the MAF sensor for $1,000. My husband figured he would take the parts out and clean them to see if that would help. Well, it's still running the same, he's resorted to driving with the OD off since the RPMs don't jump all over like they do with the OD on. Any ideas guys? I really don't want to fork over the $$ to the dealer...my husband can do minor repairs to the truck but if it's something overly complicated we'll have to take it to the shop.
