I bought an e99 auto from a friend. He bought the truck from the original purchaser. Truck is stock except for BD trans, BD torque lockup, and a 6637. Had a bd chip on it but friend took it off due to hard shifting. My issue is when it rains and I run the wipers, seems to be only on intermediate, truck bucks and cuts out. Google and I found that the ground on the wiper and ground on the pcm are shared and the wiper motor will cause issues for the pcm. Makes sense to me. So that one solved, well maybe.
Issues at this time. This truck has been going through Ford throttle assemblies left and right. Like 4 in the last 2 years. Whats the likely hood that the pcm is messing up the TPS? Maybe the wiper motor is messing with the pcm and pcm is screwing with the TPS with weird voltage or something.
Thinking I might need to replace wiper motor, or very least move the ground, buy a new pcm and have it flashed and then a new tps or am I going the wrong direction??????????? I'm not new to PSD's and the obvious things have been checked or replaced.
I'm extremely stumped, please help and TIA
