I had been having trouble with my LPG system cutting onto petrol whilst driving. Other than that, the LPG system seemed to be driving perfectly fine. (The system is a PRINS multi-valve injection). I asked J.W Auto to have a look and fix it.

When I collected the car it was immediately obvious that *something* had been done to it, as it drove like it was restricted - until I hit 3,500-4,000 rpm and it was like a turbo-charger kicking in. Driving away from the lights was torture - even buses were faster than me! The car was undriveable, and quite possibly dangerous.

I took it elsewhere, where they quickly identified it was a faulty vapour pressure switch and even contacted PRINS Australia to get it replaced under warranty. I will never go back to J.W. Auto!

I run my car on gas & petrol. The gas went on the blink... John at JW Auto Gas checked out the problem and thought it could have been a couple of things, one of which was going to be very expensive...
Rather than just changing everything and charging me for it, he took the time to isolate the problem and fix it. It didn't cost the nearly s much and I'm saving money on gas again

Approximate cost: $300
