After owning my 2000 V8 Auto for 2 month I think Ive just about got it into a state where I can consider an LPG conversion. I know from what Ive read on here LPG needs an engine running well on petrol to run well on gas so I want it right before I have it converted. I bought the car for the right money its solid and in great condition inside and out so I figure its worth doing
So far Ive replace coil packs and leads, both lamda sensors, valley gasket (due to coolant loss), full service new MOT (first time pass) and I have a new Rad on the way. Ive now stopped all coolant leaks (Apart from small one on Rad but this will soon be done). Improved mpg, now getting about 18-19mpg combined was more like 12-13.
The last and I guess the hardest problem is a lack of power and rough running under load!! Runs fine on flat powers good changes gear well. But not so good going uphill accelerates to about 30mph then just runs out of power and keeps changing down a gear then straight back up!! Engine doesnt rev over 2500rpm no matter how far I press the pedal. So am inclined to think its not a gear problem and as I said it run sweet as a nut when not under load???
Ive disconnected the MAF but this didnt make any difference so basically Im stuck? How likely is it to be the MAF? Previously I had a MAF fail on a V6 Ford but when it was disconnected it ran fine but as I said disconnecting this has made no difference!!
