Answer
Joe,
Yeah install a fuel gauge that you can see so you know if you are loosing fuel. Also read the codes and see what they say. You may find air mass meter or fuel trim codes and those could mean an air mass meter fault. If so try a known good Air mass and see if that helps. Inspect and clean the throttle housing. The carbon deposits cause stalling problems. If there is a lot of build up on the throttle plate then go ahead and do intake cleaning with a chemical that will penatrate and remove those deposits and that will also clean the intake valves. A good system that I use is the BG fuel system cleaner. That will be available from a shop only. I have never seen it in a parts store.
