duel fuel... runs like poop on petrol but fine on gas

[jakeydee]

hey all i have just recently obtained a 92 vp berlina and its on duel fuel, on lpg runs like normal but flick it over to petrol and stalls then after turning the key to start it again on just petrol it will start but run really lumpy including through revs then flick it back to gas revs even out and go up nice and smooth.?? Any Ideas as i much prefer petrol... also while fixing my power windows and brake lights my indicators now dont work..?

Your car has been run on gas for ages and the petrol injectors are dirty. Run a tank of top quality fuel through with a name brand injector cleaner (Wynnes, Nulon, etc) and you'll find it much better in my experience. If it don't improve then you need to get the injectors ultrasonically cleaned or recoed.
As far as the rear cluster goes, there's always a connection in the most inaccessable place that corrodes, it makes the whole rear light set act weird, it's fixable but someone needs to show you where to drill the plug and whatnot. Rare Spares can sell you a set for about $50 all up. It's worth doing, takes about 10 minutes to swap out.

Rear Cluster? Like The Whole Indicator system done work now.. dash dont light up no noisable tick yet all fuses are good and all the loom i went over like 3 times and is not frayed or anything... the stalk itself is fine as i can wire it to my vl and it works fine... really confused with this one.. going to take it to ma mate at th chop shop in the morning but if anyone elce has had this problem some advice would be fantastic... or if anyone has a link to a wiring diagram for it just so i can follow it properly front to back.... again.
