i have an 02 GLE, and i cant tell you whats going on but all the sudden the car feels sluggish the only codes i have for now is P2138, i dont know if that can affect the performance for the car... also my gas milage fell from 22.0 to a low of 13.9.... it it is now back up to 19.5 but i dont know what the problem could be

 

I cannot find code P2138......it's not a valid code.

 

P2138 - Accelerator Pedal Position Sensor Circuit Range / Performance Problem

i'd say that's your culprit..

 

same here ...but i have a 00' gle i dont think the codes are the same. lol

 

any idea on what i can get to fix this???? where do i find this part???

 

I would say Napa, autozone, nissan, advanced auto parts. I dont know if that would effect the gas mileage though. Seems like if it was on its way out it would actually save you gas since you wouldnt be able to give it as much gas.

Is this somthing that is conistant or is it random?

 

None found anywhere im just gonna type in a google search lol

 

Well... none in google search
