was driving down a steep hill when it first stalled on me. it still did it on flat road too. i thought it was maybe a lack of fuel because it was a hill and the tank was near empty. but under throttle it drove fine. i was guessing it was a dirty IAC again, but it seemed different this time. this time it was surging alot when not on the throttle, but under throttle it drove fine. it kept surging up and down between 300 and 2000 rpm and occasionally started to stall or stalled alltogether. could it be a dirty MAF? im gonna try and get out and clean the IAC, which i think it is because it drove fine after i turned it off and restarted it again.
