HELP, loss of mileage

this has been the second week where i have only been able to get about 260-270 on a full tank of gas(91). usually i average about 310 - 320 on a full tank(91). I dont kno what seems to be the problem besides using the AC a lot because of the LA weather. what do you guys think???

If u Use AC, it takes more gas to power it so u will decrease ur mileage.. If u want to save more gas, try ground wiring kit!! helps with the gas mileage..

YEa its normal for u to end up with a lower gas tank if u drive with ac
on.. You use more power to run the ac. thats why if u decide to race on
a hot day or something, u don't want ot have it on cuz it robs horsepower.

I've been getting about 350 to a tank with a flakey coil and nasty plugs. I just changes plugs and coils two days ago and so far(it's way early) I'm getting 110 miles on a 1/4 of a tank. I'm at 5600 feet also.

It has been stated many times that using tha AC does not use much more gas than driving with the windows rolled down. The wind drag from rolled down windows nearly equals the engine power needed to run the AC compressor.

I thought the compressor clutch cut off at WOT. Most cars do.
