1995 Ford Bronco 5.8 E4OD 6" BDS Lift 17" Method Wheels 35x12.5x17 BFG AT KO2
Frustrated as all crap over here! I have a feeling I know what the problem is, but I'm looking for other ideas just in case. My 95 Bronco with e4OD almost always clunks in the middle of 1st gear. It doesn't feel like it's shifting into 2nd when it does it, but it may simply be a hard 1-2 shift. That said, it occasionally does do it, however very rarely, in other gears. When I bought the rig 3 years ago, it was having a derby level time of fishing for idle. I did replace the IAC and TPS, along with the shift position sensor. The idle fishing stopped, but the idle stayed high and the engine light has never not been on since. I recently decided to play with that, and bought the code reader. 122, of course. I back probed, good ground and 5v from PCM. Sensor reading was essentially non existent and no change when cycling the throttle. Just got a new Motorcraft TPS, and plan to put it on today or tomorrow. It didn't come with the collar, which bugs me as I've read that a bad one could also cause TPS problems. After 3 years, I have no memory of the condition (or existence) of the one I installed to begin with. I was annoyed that the idle has been at 1000 or just above since the original "fix," so I turned back the throttle stop screw. I got it down around 600 or so, but the truck ran rough and would occasionally stall at startup and initial reversing. I could not get it to find a spot in between 600 and 1000. It seems to like being in those 2 areas and not work properly in either one. Anyway, the hope is the replacement TPS will fix the problem. Just in case, any other ideas are welcome and appreciated.
