yay winter blend gas?

**Swiggles** · 02-02-2012

dont the comp g's have 3.29 gears and get lower gas mileage? not sure if your a comp g.

it could need a tune up, and we are on the winter mix gas wise...have you been starting the car and letting it warm up for ~10mins? get the engine light checked for free at an autoparts store. you might need a new front o2.

dont just go by what the guy you bought it from said, he was selling you the car. you should investigate for yourself so you know whats from and make it worse.

**ctracer** · 02-02-2012

well you said you have a smaller pulley...i would check the tune like everybody else is saying.

**DrSnazzy** · 02-03-2012

I dont have a tuner :/

**Swiggles** · 02-03-2012

lol your in MI theres tons of people with tuners, just ask

**DrSnazzy** · 02-05-2012

Cars throwing a p0135 Code, so time to replace the upstream o2 sensor ! haha

**rodneypierce** · 02-05-2012

there is most likely your problem.

**dsmuts** · 02-05-2012

O2 might not be bad. I'm helping a girl chase a 0135 code on her ga and the o2 is new

**darkhorizon** · 02-06-2012

99% chance this is a header leak issue.

**Steel Armadillo** · 02-06-2012

this ^^

**DrSnazzy** · 02-06-2012

But the o2 has never been replaced in the life of the car :/ how would I know if its header leak

I was getting around 25 MPG with the GTP using a 3.25 pulley and I had stock injectors. Like a lot have said, think you need a tune.

Your tires would have to be flat to make you get 5 mpg worse gas mileage.

I've been getting about that much in my 2001 SE. I check for codes every month, and I haven't had any for three months. No notable power mods. It has probably been doing this for a while; this is just the first time I've taken note of the mileage and gas levels at the same time. 135 miles on 10 gallons.

**LowRidinCrew** · 02-10-2012

I got the same MPG right now, mainly because my damn transmission is ****ed up and it goes past the 2.5KRPM to keep up at 35 MPH which means more gas burned.
