I put in a new motor since the old one locked up. Since then the TB sticks and I have to pull the gas pedal back to make the rpms come down. I have adjusted both the throttle and the cruise control cables until they are both real loose but it still does it. I have a 2000 tibby, any ideas?
When I swapped the motors it originally had the TB that came with the new motor. It did the RPM thing then so I figured the TB was bad so I swapped the one from the old engine because I knew that one worked fine. It did it with that one too so I figured it was the cables. I played with them and thatb didn't work. So here I am asking for any additional suggestions
check the throttle pulleys, i had a similar thing happen to me a few times, one time my idle bypass hose was holding the pulley open. another time was after i put my dual rail in and the throttle body pulley was hitting a wiring loom that is attached to the back of the firewall.
For the first problem i got rid of by moving the idle bypass, second problem i had to remove the cruise pulley...
