I shouldve explained better, when im driving going up a hill, or say driving anywhere from 20mph to 55-60mph while im still on the gas the car will decelorate.. Not slow down it holds its speed but the RPM'* drop! I press down harder and harder and it sluggishly picks up speed, then eventually jumps back to speed when almost to the floor!
It also will pick up speed, if i let off the gas & get back on it & it acts like it should.. Any thoughts!!???

Pull the vacuum hose off the fuel pressure regulator and see if you smell gas in the hose. If you do, replace the FPR. Normally I would think you are experiencing a misfire, but you did not mention the check engine light coming on. If the check engine light is coming on, or flashing, you have a different issue.

Nothin in the fpr line, but it looked old, had some kind of green build up on top of it like what comes on the battery post... So i swaped it, & problem is still there

Ok, a little update. Read online sumwhere that this could be the "Tcc" in the trans & a way to kno would be that when it does the rpm drop lightly tap on the brake with my left foot and tcc will re ingage and rpms should rise back up.. And sure enough IT DID..
My question now is how many sensors effects this!?
& would changing the speed sensor on the output shaft be a good start?
