Okay the cut out open I pull 296 on a tank... Normal before cutout 270ish. Now since I ran sea foam I pulled 200 and this tank 241.... Now the cutout is closed on the 241, but my mileage has gone to the pot...

Plugs and wires not 4 months old
No hesitation and running 93
Normal Temps too


I am running the AC more than usual, but can it be that much of a difference.

 

Coil? Fuel filter? Driving habits(been getting on it more lately?). A/c makes more of a difference than you'd think, especially if you're driving mostly around town. Can cause up to 2-4 mpg, which would be roughly what you described. If it's not too hot just run with the windows down, only use a/c as necissary(that's what I always did). I usually got around 300-320 a tank on my 94, but I barely ever used the a/c.

 

WTF? Your car was fast as F*(K, and got awesome gas milage??!?!! What a freak!

 

How many miles on your car?

O2 sensors?

I'll trade you my camaro, I managed 400 miles one tank diving pretty serene with a few WOT, and only about 100 miles on the highway.

 

LOL

driving around town i'm lucky to get 200mpt... usually 190... and i wait till there is 2 gallons left.

thats about 14mpg i think

on the highway i got 21mpg

 

The most I've got was 280 miles when the needle was between 1/4 and E.

I always average been 22-23 MPG.

 

Jeeze, I've hit 400 on a tank before.
It was on the highway though. Right now the check guages light is on and I only have around 180 on it though.

 

LS1's don't count My broh's 98 6 speed consistantly got high 20's in the city and close to 34 on the highway. Even though my car got good gas mileage for a V8 his car just made me mad! But my car was faster, so it was all good
