90 and 91's had a manual throttle option that was discontinued for the 92 and 93's. The parts are still available thur Dodge. The fuel(gas) pedal assembly changed in 92 but the manual throttle parts will still fit with just slight modifications. Set the idle high on those cold morning and go back inside for one more cup! Might be something to consider adding if it gets cold in your neck of the woods.
