G'day all,
Ok I have this problem with my 94 GQ 4.2 duel fuel, I've seach the best I could on the net and found nothing, taken the GQ to a recommended mechanic which I found to be a great service, we cleared the cars computer and he told me to bring back when fault occurs again. It happen 2 weeks ago, check light on dash came on when stalled, took back to mechanic and there was no faults on computer.This is the GQ's problem and it happens on both fuel, I will be cruzing along and engine starts surging and eventually stalls( temp on gauge shows 3/4).Now I will have to sit and wait about 20 to 30mins before car will start, engine will choke and hesitate abit until I get to about 30kph and then drive like nothing has happened and might not happen to the next family trip away which could be months . Last week at mechanics he change the LPG mixer(TIPO MPP) coming from vaporizer to a brass valve tap that is manually tuned and I was wondering does the new fitting affect unleaded fuel as problem is happening on both fuels. Also I changed the waterpump, fan,fan clutch and coil. This problem has happened 4x4 over rough gound, sand and on bitumen, normally warm over 30c and problem never happen on a cool day or nite.
Thanks.
