MY DUAL-FUEL 1996 EL Falcon sometimes behaves as if the auto has dropped to a lower gear. It slows slightly and the problem continues for a distance. I take my foot off the accelerator until the problem fades. It usually happens after the car has warmed up. Any idea what it may be?
IT SOUNDS like a fuel-supply problem, so check that first. The LPG mixer is most likely the culprit.
