miles per gallon?

**backinblackgtp** · 01-11-2010

since i have bought the this gtp in late October i have been getting an between 13- 15 mpg city driving, i have minimal mods, and i don't have a heavy foot. Is there something that should be replaced that's causing this? 45 dollars a week driving only 130 miles is alot. thanks in advance

thats not good with all my mods and a mildly heavy foot im getting 16-17 city right now with a cam code

maybe time to change out the front o2 sensor fuel filter maybe swapping out plugs depending on how old they are maybe
How many miles are on your car

are you getting any codes? the front o2 sensor might be dying.

he lives right near me. he was getting codes for the rear 02. but his SES light is off now. I was thinking the front could be on the way out

almost 86,000 miles, i just had a high flow cat and resonator put in a month ago, and i know before i bought the car, the carfax said the exhuast system was checked several different times but still, i dont think it could be that? so you all recommend new spark plugs, new front 02 sensor?

**cerick08GP** · 01-12-2010

Yup, plugs and the front O2 sensor are basically the only “tune up” stuff that needs to be regularly replaced on our engines. Each last about 100k, more or less. The only other item that could done is cleaning the MAF sensor.

**backinblackgtp** · 01-12-2010

well i know the MAF sensor has been replaced its not the original one, and the guy i bought it from said it was recently changed. so ill change the front 02 sensor and plugs, gonna be annoying rocking the engine forward for the rear plugs

Its not that bad
Im going to be lazy and buy the engine moving tool
its only 35 bucks at matco tools for students ya its lazy but id use it

**mikesarebetter** · 01-12-2010

having the right tool for the job is never lazy!!

**TorqueAutoMotiv** · 01-13-2010

Im actually ordering one when i get my next check i remember the first time i changed plugs i had my 1/2 drive rachet proping the engine forward not smart not safe but it worked

**rynoman03** · 01-13-2010

Rachet strap from the engine mount to the radiator support area works wonders too and costs less than 5 bux.

**TorqueAutoMotiv** · 01-13-2010

theres a chance of bending something that way though i know its slim but still

**backinblackgtp** · 01-13-2010

ill probably have it done at a shop, don't need any more problems with my car than i already have.

**blueguy** · 01-13-2010

Be a man...change the damned plugs.

**BwolfGT** · 01-14-2010

Mine's been doing the same thing for awhile now, finally threw a code for a bad cat the other day. I'd try that and the o2 sensor, and some injector cleaner.
