Hi
I have just bought a 525i SE 4 door saloon 1989 and would like to know if anyone has converted one of these to run on LPG. This car has been converted already before I bought it and will run ok on Gas but when switched over to run on petrol seems to develop a misfire and wont pulll like it should. I have fitted the original airbox back into place as it came with a K&N filter instead and I was told this would affect MPG so on this advice I changed it back to original airflow meter and box still to no avail. The car still seems underpowered even on gas which makes the juddering and misfire disapear. I would be greatful for any advice from anyone with knowledge in these matters . The car is just shy of 156,000miles and still sounds sweet as a nut Regards Stevie
