Hey guys, I have a 97 base 5spd with 114k miles. Every once in a while after shifting back to neutral, my rpm would dip down to 200-300 rpm, i can feel my car sputter and choke. Then after a couple secs it would climb back up to 500rpm. Friends tell me it could be dirty oil, but i'm suspecting clogged injectors or a bad IAC valve. Anyone else experience this problem?
