I have a 94 f-150 with a 5.0 4x4 and auto trans with OD. the problem is when you take off it holds in gear to long before it shifts up. I replaced the throttle position sensor because it gave a code for it. After install on a 2 mile test drive it shifted perfect the a few miles later the check engine light began to come on and go off frequently and the shift problems returned. can someone please offer some advice it's driving me crazy.

 

Any new codes?
