This fuckn car is going to kill me
The car dosent even brake well when the pedal or acceleration cable gets kind of stuck
I already tried cleaning the TB. How do I un-tighten the acceleration cable?

I dont understand what this means by:

Insert .006" (0.15mm) feeler gauge between the throttle stop screw and throttle lever

I know what a feeler gauge is, but what does he mean by "throttle stop screw and trottle lever"?
