SOURCE: 2000 Mitsubishi Eclipse will not idle, all else OK, just repl bat

I can only offer these few ideas.

  1. The TP throttle position sensors for this year group fail often Pin 1 to Pin 4 resistance should be 3.6 to 6.3 ohms but you need to remove the two 7mm bolts that hold this sensor on the front side of the throttle body, then rotate the two bolstered center and see a change in resistance from low to high. If the resistance remains fixed, the sensor is rusted out and must be replaced.
  2. The IAC motor is mounted on th LH side (driver's) of the throttle body. It should make a clicking sound when the key is turned from Lock to Run. Pin 2 to Pin 1, Pin 2 to Pin 3, Pin 5 to Pin 4, and finally Pin 5 to Pin 6 must all have continuity at 38 to 52 ohms.
  3. Check for any vacuum leaks.
  4. Remove clean and check EGR.
  5. If this is a Cranks but will not start problem, check the owners manual for Theft Deterant UNLOCK proceedure. If there is power at the rear fuel pump relay coil and no power at the MFI/ASD front relay coil and no spark, then its the security system.

SOURCE: My 1999 Eclipse gs engine light came on, DTC P1390.

P1390 - Timing belt skipped one tooth or more.


the engine is an interference engine so if the timing belt skipped, it should be fixed before starting the engine again. otherwise you run the risk of bend/break valves from piston to valve contact

2001 eclipse engine dies when acceleratoris not engaged. Engine will not idle.


Idle is controlled by idle air motor and they can get dirt clogged and be cleaned. Of course, all tune up items can also cause this, as well as bad O2 sensor, TPS, EGR, and others.

Sounds like the clutch assy is about worn out. Most hydraulic clutches are self adjusting so when the clutch disc lining wears thin it takes more pedal travel to engage.
