#34 of 99 exhaust manifolds by saab2 Jun 22, 2007 (3:18 am)
2002 F150 with smaller V8 began to make expensive exhaust noises under the hood at only 35000 miles. Since it was out of warranty I first took it to a muffler chain for their estimate, $600 to replace the manifold which had a visible crack. They said odds were good the other side wasn't far behind. Went to my Ford dealer and politely expressed my displeasure at things falling apart this early. They did their exam and said that not only was the obvious side bad, but the other side had 2 broken studs and was going to go soon. The good news... Ford picked up 2/3rds of the $1500 cost. It shouldn't have let go this early, but they did stand behind their product so I got the work done there, all is well for now.

Replying to: armstrongr (May 23, 2007 7:20 pm) it could be your stater, which is located inside your distribitor.

#39 of 99 F150 EGR VALVE by troutfisherman Dec 19, 2006 (11:41 am)
I have a 97 F150 & the EGR valve has been changed out twice and it still shows a problem with the EGR valve. I even checked the throttle body for plugging but it was clear except for a little build up on the wall. Any info would be greatly apprecated.

Replying to: troutfisherman (Dec 19, 2006 11:41 am) Did you have an diagnostic run on this? There are several parts for this - EGR valve, EGR vacuum regulator (EVR), differential feedback pressure sensor, the PCM, EGR pipe and various vacuum and pressure lines. The diag test should have given codes for the specific part of the EGR system.

Replying to: nofear3212 (Apr 29, 2007 7:35 pm) I have very similiar problem. I have the 0403 "EGR excessive flow" problem. Have changed the DFPE sensor, EGR vavle, and EGR tube. Check engine ligth still stays on. Mechanic has check the EGR system and says it working ok, he says its the PCM. I don;t want to change a $400 PCM unless I know for sure what it is.
