Hi all,

I have a 1996 2.4L Magna. Suddenly the other day (on the way to the airport - best time) my Magna would not idle and stalled immediately upon starting up.

This continued until I found the screw that adjusts the tension on the throttle lever/cable on the throttle body. I was able to up idle speed, but of course once the thing warmed up I'm riding the brake in traffic. Also, it seemed that idle speed continually dropped back with every adjustment of the screw - is it compensating?

Eventually I unplugged what I believed was the idle control servo motor on the underside of the throttle body and the idle remained as set by the screw.

If it helps, my car was converted to LPG 7 months ago (could gum up the idle motor?). I did try resetting the computer by disconnecting the battery. I deliberately started the car with the battery reconnected with the Air-con ON, so it's at its highest load & idle should be upped accordingly. With idle motor reconnected, the car idled fine on its own until I turned the aircon OFF and it stalled!

Is the computer sending wrong signals to the idle motor? I was thinking of what signals may affect idle and could really only think of aircon and water temp. Does anyone have any suggestions? It seems idle IS being adjusted, just way over-compensating for some reason!

Cheers,

I would bring in to the LPG place. I had some issues with my car and it was LPG related. Since it takes time for the LPG settings to settle in I would suggest bringing your car back to them to inspect.

Hi,

I suspect the LPG too because I know it sometimes gums up converters.

The car is duel-fuel, and the problem is there when it's running on Petrol as well.

I know it's only a 2.4L on gas, and I'm the one that got the conversion done... yes I know, I'm a tightass!! I don't recommend it, the car is totally gutless on gas, even worse than on petrol. Don't expect to climb hills with the aircon on and gas too!

Brett.
