im gettin a trouble code on my S10. its P0440 Evaporative Emission Control System Malfunction. i checked my haynes manual and all it says next to the code is EVAP. thats all the advice it gives. im thinking maybe the gas cap is leaking. its been doin this for a few weeks, and the SES light goes off after about 10 minutes of driving. any advice?
