Hi, My 90 Integra Xsi is smooth in the morning for 20min. After it reaches its temperature and car warms up, the car idles between 2000 - 3000rpm, it doesn't go smooth the car just keeps pulling back. I have to drive my car past 3000rpm for it to be drivable. As the car gets warmer it gets much worst but only between 2000-3000rpm. I have been given the run around by Mechanics, exhaust specialists and auto electricians. The Insurance people said it was my distributor bearings. The Mechanics said it was 90% my exhaust and that I should see an exhaust specialist. The exhaust specialist said it was definitely an electical problem. I went to Honda and they said it was definetly electrical. I went to an auto elec and he wants to charge me for a distributor and a throttle body. I'm sick of these rort ass incompetent mechanics!!! Common sense wise I'm thinking its something as simple as cleaning the throttle body. What do people think?? Thanks
