Gr. Voyager 3.3 is starting to use too much gas!
Guys,
Need you advice. My Grand Voyager-96, 3.3 engine start use too much gas. Usually I could take ~ 250-280 miles per tank. Now I can hardly take ~150-160 mi/tank...  I changed air filter, checked the tank cap (it fit well), there is no any leak... What else should I check? Thanks, Eugene

Re: Gr. Voyager 3.3 is starting to use too much gas!
Welcome to the forum. I would connect a scanner with a real time data capability to determine where to look first. Shooting from the hip I would suspect the upstream O2 sensor first. It is a key component in determining fuel/air ratios. You haven't just started using your A/C now that spring is here have you? How old are the spark plugs?

Re: Gr. Voyager 3.3 is starting to use too much gas!
RIP, thanks for the reply.
1. Spark plugs are 3-4 y.o. Is it time to replace it? 2. I have not yet started to use A/C. I do not think it is related to A/C... 3. There is no warning message on the main board. 4. Forgot to mention. When I start a car or press gas I can hear the more stronger noise (like B-r-r-r) as usual! I will change the O2 sensor, of course. Eugene
