This is a very strange problem, but my 1994 940 NON-turbo wagon sometimes drops to very low RPM's while driving, has no power while pushing down the gas pedal. This happens while turning RIGHT ONLY. The engine does not stall, but just seems to be in NEUTRAL for a few seconds and it just coasts. Anyone??? I have had the relay and fuel filter replaced, and had it looked at by a VOLVO repair shop (Not a dealer shop), and a great mechanic to no avail. HELP!
