Default Any ideas?

My mileage is scary low.
In the last couple of weeks, my mileage is so bad I'm starting to think I have gas leak or there's an elf siphoning gas out of my car.
I haven't been as lead footed on purpose since I realized this.

I changed to a Corsa Pace Car exhaust several weeks ago, but this started happening recently. I filled up my tank one night, drove 36 miles the next day (not WOT even once) and my gauge says I used 1/10 of a tank. WTF?

The only thing I did recently, was replace the fuel fill pocket (plastic surround that holds the filler pipe in place). The fuel hose was in good shape, etc.

I don't smell gas in the garage, nor are there any spots or fuel smell in/near the car at any time. I'm wondering if anyone else has experienced this or similar? Do I need a tune to adjust A/F mix or what???! TIA gang.

Dave Q.

Dave

I would have your A/F looked at. Although I seriously doubt that your gas mileage would suffer that drastically without you smelling the Shell station strapped to your back bumper

Let us know what you find out

The pace car Corsa's did the same with me - but I think the fact that I drove around in 2nd gear (A4) for the first month had a lot to do with it.

Hope you solve it soon.

Could it be the gauge going bad and not really using the fuel? I'm with you that you'd smell it if you were leaking or burning that much


Good luck....PS....any pranksters around that could be messing with you?

Dave, 1/10th of a tank for 36 miles? That's 360 mi a tankful, doesn't sound bad for city driving.

That's about 20 mpg around town...not to bad if you ask me!
Then again, how much weight did you say your right foot gained?

Thanks Jim. I hadn't looked at it that way.
Come to think of it, I hadn't really paid that much attention to it since I did the fuel pocket repair.
It's funny how perception changes when we're looking for problems.

I'll take that! I have a Stinger intake and Stinger dual exhaust (MN6) and seem to only average 18 - 19 City driving.
