hey guys, I just took my car out of storage from the winter, got an oil change put on a new set of 245/40/18s and on my first half tank of gas i managed to get 62miles out of it :S , yes i drove it a little hard but nothing more than usual... would this be normal for the car since its been parked for 3 months ?

usually i get about 120 miles at half point.

 

did you have the battery unplugged? If so, the fuel trims are resetting themselves. Should take 2-3 drive cycles to bring back to normal.
Also, try cleaning/changing your air filter and cleaning your MAF sensor

Also, may want to do the 20 break pedal stomp to reset the ecu

 

20 break pedal stomp....?

 

No the car was never unplugged, I went to start the car every week during winter, now to reset the ecu , do I stomp when the car is running or in the on position and how do I know when it happened?

 

I dont know why / what purpose this would serve?

 

lol did you answer your self ?

 

This procedure is to reset the ECU to factory settings. it will clear fuel maps and such...

From off, turn the key to the on position (but keep the engine off). Then immediately and rapidly tap the brake pedal approx 20 times or until the ECU resets. when the ECU resets, you will see the oil guage sweep all the way across and back.

 

thanks man

 

no problem. I live in texas so I dont have to store my 8 for the winter, but that seems really weird. did you have a full tank when you stored it or did you fill it up when you took it out of storage?
