How do you drive or what is your driving style like?

Are you constantly trying to go around people, do you drive with the flow of traffic, or are people constantly trying to go around you??

Have you tried connecting up a vacuum gauge, driving around with the gauge in the car to see if you are getting normal readings? Or just hook the gauge up, start the car and pay attention as to how much vacuum you are pulling at idle, at 2k rpms... Best way is for the engine to be under load when trying to diagnose with a vacuum gauge.

BTW, driving with a vacuum gauge can very much benefit you in trying to get good mpg. I just connected one in my car about 2 weeks ago, and so far on this tank I have 177miles and I'm only at 3/4 tank to go... Driving style will affect gas mileage probably more than anything will.

Allright, didn't figure you drive crazy... How about your MAP sensor? If it's out or going out, your ECU will not know how to adjust A/F and timing and could be running some sort of standard baseline as if the car is in open loop. Are the fumes from the exhaust very gasoline smelling? Or does the exhaust smell normal?

I'll have to do some more searching as I wouldn't even know what numbers I should be looking for.

Thanks

I'll help you find a link... the vacuum gauge is really only going to tell you how healthy the engine is....
