1994 Toyota 4Runner ProblemsDriveability Concerns Due to Throttle Position Sensor Out of Adjustment
The Throttle Position Sensor can get out of adjustment due to wear in the throttle body or due to carbon build up. This will cause the idle timing to advance more than 30 degrees which will cause very high HC and NOx emissions. Conversely, the Throttle Position Sensors can wear out and not properly advance the timing which causes a lack of power and poor fuel economy.
At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.
At 125,000-150,000 miles, the Master Cylinder may need replacing. It is critical to adjust the brake pedal to Master Cylinder pushrod clearance or the brakes will drag and over heat.

The car still won't start. it did start and i took the jumper off but when i turned it off it won't start back even with the jumper
It has a V6. The alternator belt was bad so I thought I'd change all the belts at the same time. Maybe someone can give some advice on how to get that pesky ac belt on? Thanks for any advice!
