I've been driving around for 2 months now... after replacing the engine ... the first problem i have is after at a stop light i go to take off and the car stalls once in awhile... points me to the throttle position sensor ... 2nd is when i hit over drive speeds my car will shift back and forth between gears when i'm not above 85 with the slightiest movment of the pedal... again it seems like the tps.... now i've swapped tps from my other engine , all i can think of is the throttle cable adjustment . is there a certian way the butterfly valve lays or is it dead shut when adjusting it...
