Car will not move when it is in gear and gas pedal

I need the exact year please.

Could be a bad clouch

If its been without the line for over a year, I Highly doubt it. Look into IAC valve. Most are installed with 2 screws, easy to adjust. Idle Air Control Valve. Look that up, for a start.

check your throttle pedal position switch and your throttle position sensor

Clutch plate and pressure plate seem to be too weak to pull the car. Or one of the CV joints is detached from the gear box. To test the clutch plate, park the car on flat surface. Pull the hand brake up, start the car, depress the foot brake pedal, depress the clutch pedal, put the car in 1st gear, press the gas pedal and leave the clutch pedal at once, while keeping the brake pedal depressed.
Follow one of the two following statements:
1. Engine does not shut down and remain start. (Clutch plate, pressure plate and clutch bearing defective - Replace all as a set)
2. Engine shuts down. (Clutch system is OK and does not require any repair).

Modern vehicles are bristling with sensors, all reporting to the Engine Management System. These need to be inspected, for possible loose wires, bad connections or even broken wires.

U NEED TO REPLACE THE CLUTCH PLATE MOST LIKELY

sounds like the clutch is worn out and requires replacement.

may have bad gas pedal sensor, or throtle body motor, thats only if you step on gas pedal and engine wont even rev up, if it rev then possible trany problems.

tighten throttle cable behind airbox, change oil 5w30 and filter K&N. at fill up put lucas tune up in her.
