1999 b3000 with the flex engine. I have a few problems. I have replaced the IAC and it has newer motorcraft plugs and wires. First problem I have is sometimes when I am coming to a stop, disengage the clutch and coast the idle drops to 400-500rpms and the truck seems like it wants to die. even makes the oil pressure gauge flicker.
Second problem is if im running down the road, doesnt seem to matter what gear, if I let off the gas there is normally a 1 second delay before the engine actually stops pulling. Ive also had it where the engine will seem to keep pulling/maintaining speed up to 5 seconds after i have completely let off the throttle.
Changed the Iac, checked for vac leaks, getting ready to install a new pcv, fuel filter, and clean the throttle body. Ill report back with those.
