sounds like a stuck throttle body or tps sensor issue to me. everything else is just a matter of a cable and that shouldnt cause the issue

exhaust leak wouldnt cause that, and thats a lot of miles which means a lot of use on the tps and throttle body. i would take the intake box off and look under the hood. have someone step on the throttle in the car while the car is off. see what happens.

try cleaning the throttle body up, might have a lot of build up and sitting causing it to stick

but my guess is a issue in the tps, but the other checks are free to do

ok well my guess is tps then, it has to be a throttle issue. check your throttle cable out and make sure its working right. all thats left after that is tps which is semi common to go bad



corrected, i f**ked that up

ok lol i was just saying its hard to get to, since the air intake is on top of the throttle body, one of those weird throttle bodies, but looks like the throttle body has to be cleaned so i am going to figure out what to clean it with

if you are still able to move the throttle body with the gas pedal, than i don't think there is any issue with the cable.
i think someone already suggested this, but have a buddy monitor the throttle body movement while you are in the car, pressing the gas pedal. If it opens and closes like it should, then everything is mechanically sound.

if this is the case and your car is "jumpy" with just a light touch of the gas pedal then it sounds to me like your TPS is starting to go...

if you look at where the throttle cable connects to the throttle body, you'll notice the cable kind of wraps around a wheel, which turns the throttle body. If you look on the other side of the TB, you'll notice a sensor on there. It helps the ECU to monitor the "position" of the throttle.
