my 94 X with an auto tranny and 121,000 miles is getting very bad gas mileage. When i first bought it at 102,000 miles, i could go about 250 on a full tank, maybe more if i ran it past a quarter tank. now i can only go about 200-210 on a full tank and thats with it almost completely on empty. the following is a list of repairs i've done:
new spark plugs (autolite double-platinums)
new plug wires
fuel pressure regulator
fuel pump
fuel filter
iac valve
195 degree thermostat
air filter
changed oil regularly
egr dpfe sensor
ran seafoam through the engine and fuel system
reset computer
no check engine light - ran self test and came up with no trouble codes
i run 89 or 93 octane and i'm reasonably light on the throttle
I have no clue what to do next. the truck runs good otherwise. I had a 93 xlt with a 5spd that had 210,000 miles. The truck burned a quart of oil every week and i still could go almost 300 miles on a full tank. I just wish i could get that kind of mileage now. The only thing I'm wondering about is that i put a brush guard on a couple months ago and I'm wondering if the added weight on the front end would affect my mileage this much. Also, are there any aftermarket bolt-on parts I can do to improve the mileage. I'm looking into upgrading my exhaust, should i expect any improvements? Any ideas would be greatly appreciated.
