Hey all, I have a 1999 F250 SD V10 4x4. I recently had a transmission installed and the truck is running erratic. I have an engine miss (sometimes when idling, more so when in drive and foot on the brake). I say sometimes because there are times it will not miss and the engine runs smooth. The transmission shifts a little strange and sometimes hard.

I am getting a code reading that says my TPS is faulty, but I installed a new one a few months back.

The engine is running rough (jerky on acceleration) especially when driving. I was wondering if I should take it to a shop and have them flash the computer to reset it?

(Side Note: I also remove the AC compressor a while back (bad clutch). No $ to replace. I installed an aftermarket pulley.)

Any suggestions on this?

 

take the truck again for a good code reading
But before that, reset the computer by disconnecting the battery negative wire, wait 5 minutes and put it back again and check if the truck will work better or not

 

Once you remove the battery cable there won't be any codes to read. You don't flash the computer to reset it, you remove the negative battery cable.
