ML 430 lack of power, missfire

[winslo]

Hi i have a ML 430. Has a lpg conversion on it and has been away for a serive due to a bad miss at low revs on gas. Had it back 2 times and still no better. But it has come back worse than when it went. It now runs terrible on petrol. It stutters, and misses. This morning on the way to work it would get to about 3k and just die, no power at all. then it suddenly started working, but not very well. Sometimes when you accelerate from standstill there is very very little power and hesitant to 3k then it takes off?
It has just had new leads, new plugs, new oils, fuel filter and fuel lines??

Anyone any ideas?

Going to try and get it onto the MB star computer this week

Take a look on the engine and find the MAF 116 in the link, unplug it and try the car

This sounds very similar problem to what i'm having. Did you manage to sort the problem, if so what was wrong with it.

I've just converted my A150 to LPG, it's an 07 plate.

I've read alot of threads about LPG and the mention of a MAF, can anyone tell me if I have one fitted to my car.
Cheers
