Hey, got a '90 Accord w/a 2.2 sohc. My idle jumps between 1500-2000 constantly. 1500,2000,1500,2000. Its annoying the hell outta me. I have personally seen a 91 civic dx and a 88 Prelude do the EXACT SAME THING, so I hoped someone on this forum is familiar with this situation. There is no check engine light, and the car runs perfect. Just idles like shit. I am thinking its the idle speed motor (idle air motor) or maybe TPS. Help me out! Thanks.
