Hello, so I've noticed a very strange problem with my gas pedal being extremely stiff only while the engine is running, after searching on this forum and a few others, I have inspected the tb and it seems smooth and the cable seems smooth as well which leads me to believe something else is going on here. As stated when the engine is off i can press the pedal and its very smooth as it should be but as soon as i start the car it stiffens up dramatically. Anyone know what could be causing this? I would greatly appreciate it thanks.

Also needing some t5 help: https://www.thirdgen.org/forums/tran...need-help.html

thanks again,

Edit: Found some info on another site, is there an adjustment on the tb for the blade position? and if the blades are traveling to far closed could this create a vacuum or something causing the stiffer throttle while running?
