Unleaded guzzler on gas
My 1999 3.2-litre V6 Rodeo has been running nicely on LPG for three years but it is now using about half a tank of petrol per two tanks of gas. I have pulled the petrol pump fuse but that makes no difference. I notice the injectors are running when it is on gas, but I don’t know if this was previously the case. If I put a solenoid valve in the petrol line the injectors would be running dry, which might not be good for them. Nobody seems to know what to do about this. Where do you suggest I start looking at this problem?
Phill Higgins, email The Rodeo has a known issue that can increase the petrol consumption while operating on LPG, as you describe. You need to take it to a reputable LPG mechanic, preferably one who knows the particular system fitted to your vehicle. DOES NOT COMPUTE MY VZ Commodore is really tough to restart if left sitting for between 15 minutes and an hour and the powertrain warning light comes on. If I turn it off and then on again it starts normally. It’s done this for three years now and no one can tell me why.
Kimbuckby, email Turning the car off and on again reboots the computer, so it sounds as if it could be a fault with the computer or one of the sensors feeding information to it. Have a mechanic check the system for faults. RUN, DON’T LIMP For many years now my 2007 Nissan Pathfinder has been going into limp-home mode. It has not yet covered 110,000km and the fault has occurred eight times in the last 10,000km. It’s very dangerous, particularly when it happens while overtaking. Nissan has not issued a recall to fix it which leads me to wonder whether other manufacturers recall cars with dangerous computer systems.
Frank Horgan, email Recalls are mostly to fix potentially dangerous problems and all car makers have them from time to time. I would say that your car has a particular problem with its computer system and I am amazed that you have put up with it for ‘‘ many years’’. Take it immediately to a Nissan dealer or to an independent Nissan specialist to identify the problem and fix it. CLUTCHINGSTRAWS A friend told me he was having trouble changing gears
