What gas mileage is it getting, I need to know how much it is getting and how much it used to be getting so I can start to make educated guesses on what to check.

Im asking what you got before anad what your getting now.

Driving habbits affect gas mileage, which is why I dont want to use the stock numbers.

I have to decide how severe it is so I know what parts to look into.

I bought it used so I dont know what it got before. I tried alot of things, air filter, plugs, wires, gas treatments, pvc valve. The check engine lighht was on when I bought but went out after I changed the wires. I'm stumped, any ideas?

You smell raw gas?

Tranny slipping?

Could be a bad o2 sensor, they go bad and dont throw a code some of the time, could even be an exhaust leaking turn it on and go under it and feel for exahsut, smell for it or look for steam on a hot morning coming out from the leaks.

Thts around a 5mpg drop. You did not mention the mileage and it could be the o2 like blackop555 has ais. Also check for the small things like air filter (gat a k& N) or big things like ignition timing. Also see incorect idle, low tire pressure, dirty injecters (you already got those) or other problem in fuel injection. One last thing, does it have after market rims or low pro tires? They can have a large impact on MPG
