RE: what's up with my mpg?? getting only 15!
hmmmm....that's what i said...did any of u guys try putting in those fuel injector cleaners that
you can put in the gas tank after filling it? also someone told me that mixing 2 gas types like a 89 and
a 91 increases the gas milage...is there any truth to that?

as far as i know, the gas cleaner goes in when the tank is very close to empty, not after filling the tank
and as far as mixing it...mix 91 and 93 if anything
anything under 91 aint touching this gas tank...

What kind of gas do you put in it??
Could be old/lazy pre cat 02 sensors like jest said, they dont normaly set off a CEL until they are completely dead or lose the signal.. I replaced pre cat 02 sensors on my nissan at 117k miles even thought there was no CEL and noticed a huge gain in mpg. Deffinately run a few doses of some injector cleaner.. Check air filter... Spark plugs and any other obvious stuff i didnt mention.

RE: what's up with my mpg?? getting only 15!
a little cheat here, remove both o2 sensors from the rear "next to the cat " tie them up out of the way and blank the pipe obviously and the system cant log equal data because that's how they work then blank the EGR valve
