Car Dies when revs drop

[ZA Steve Irwin]

Hi

Any ideas. When the car is cold everything is OK. (The car has always idled at 1000 without A/C and 800 with A/C on- is this normal?)

When the car gets to operating temperature and you are driving and you put in the clutch and allow the revs to drop, they drop to zero and the engine stops. It does it with the A/C on or off ( slightly quicker when the A/C is on).

The strange thing is it does not do it when car is stationary, then the revs drop to 600 and recover to about 800.

First place to start is to check the tps, idle switch and idle speed controller operation and if everything is functional, adjust tps and idle speed.

Hi

It may be that the idle needs adjustment.

This can be real hell to get right.

When the car is cold the warm up pellet system holds the throttle open untill the water temperature heats up to operating level, This explains why car runs fine when cold as its held at 1000rpm.

Once operating level is achieved the warmup blade on the throttle releases to the set idle which is seperate from the warmup idle, if this is below about 650 rpm the car will try to stall either stationary or clutch in.

You must set up the warm-up idle correctly, then allow it to disengague at operating temperature and set the idle. Its hard because the warmup and the idle can effect each other when adjusted.

Warmup at around 1000 - 1100rpm, idle at around 850 +/- 50

Aftermarket BOV? Most mitsi's have issues when you put an aftermarket BOV in that when you come to a stop and put the clutch in the revs drop...
My old Evo did that...
