Whats it like if you unplug the MAF?

If you can get the codes read as well, that would help

Where abouts are you? Many of us here have code reading capabilities, hopefully someone is local to you :y

yes oh yes the baby running well.i found a vacum pipe broken on the LPG system so the manifold was drawing to much air.replaced the cam sensor and then found that when the engine is switched from petrol to LPG the cam sensor shows up as a p code.possible because the petrol injectors are turn off and the LPG injectors are turned on.what a headache all sorted thanks for your advise

HELP the engine will die at 1500 revs.you can rev the engine to 2000 and feather the clutch.is it possible that the spark dis could be breaking down or could it be a sensor or mas air flow.this is now doing my head in help ps its a 2.2 16v ecotec :'( :'(

Try, as TB suggested earlier, unplug the MAF sensor and see how it runs.

just unpluged the maf but still runs the same. the rough running is on petrol and lpg so i can rule out injectors

Check all vacuum connections are secure especially on the lpg system to inlet manifold.  :-/

But you still might have a leak. Get some carb cleaner spray, let engine idle, spray the cleaner around the various vac pipe vicinities, if the engine note/speed changes, you`ve found the leak

sorted found the fault to be dodge wireing on the lpg system.repaired that then found that the muppet who had fitted or repaired the lpg vapourizser  had put the water pipes to cool and not heat so it was freezeing up.all sorted now thanks for your good advice alex :y
