hey everyone my friend has a 00 GSR, with DC headers, stock intake, etcc and aEM FPR, recently his car has been sitting for the last 7 months due to a suspended license ..and well .. a flipped gSR .. now he's getting CEL 90 whenever he drives aroudn 80 MPH .. he resets it and it goes away but it comes back on, any idea on how to fix this ?? thanks

 

also how do you fix it ??

 

too much fuel??? not enough air is one thing i would look at. but thats really odd.

 

MIL code 90 -

Evaporative Emission Control System
(leak detected in the fuel tank area)

Has your friend done anything to the car lately?

Could be as simple as tightening the gas cap, or as complex as a bad seal somewhere.
