I have a ED I6 on LPG, runs good on gas but hasent run on petrol for 2Yrs wen i got the extractors put on i changed the O2 sensor & no change. Fuel pump & pressures fine. I tryed a different MAP sender no good. Will start on petrol revs 2 bout 2000rpm then stalls if i put my foot down it coughs & f@rt then stalls. Been riped off by one mechanic saying it was fuel pump but wasent

please any help its been 2Yrs i tryed every thing in the book i can do myself.

I'd say your injectors are sticky or full of s**t. Take em out and give em a decent clean. Wont cost too much, so worth doing even if it ends up not being the problem.

yes injectors for sure if it can run on petrol add some holden top engine cleaner to the tank ( follow the instructions!!!!! 0 and let it idle through for a 1/2hr or so and then take her for drive

change the fuel filter. check the condition of the fuel, make sure the lines are clear

cheers to all for the help was injectors runs on fuel now.

thanx heaps.
