I own a 1998 Landcruiser GXL 6 cylinder auto petrol wagon with dual LPG fuel in great condition which has had regular scheduled services. I bought the car second hand in 2002. Its has done 172,000km. About 3 months ago I noticed the car start to shudder when stopped at lights and when idling generally. Whilst driving normally the car is fine, but when stationery it shudders so much it almost feels like it wants to stall. This happens in both petrol and LPR mode. Also, a couple of times when on gas and after accelerating, then breaking and turning, the car has actually stalled, which isnt much fun when travelling at 60km/hr (drop it into neutral and restart!). I took it to a 4x4WD workshop and they couldnt work out what was wrong. Said it might be a sticky valve but they didnt inspire much confidence in their reponse. Has anyone heard of or had a similar problem and could shed some light on how to fix it. Appreciate your comments. Cheers. Mike
