2000 SSEi idle surges
The 2000 SSEi has developed a wierd engine surge when idling afer you just start it and the engine is warm. It rarely does it, but it does every once and a while and it doesn't give you a great feeling. The normal idle speed is 800 RPM on that car, but sometimes it'll surge between 800 and 1,000 RPM extremely quickly. You can sit there and watch the tach jump up and down really fast and you can hear the engine, it sounds like somebody tapping the gas pedal on and off really fast. It sometimes does this bad enough the engine sounds like it'* going to stall, then all the sudden it'll jump up to around 1,800 RPM, then drop back down to 800 and it'll be fine after that. It is really wierd, but everytime it happens it lasts for the same amount of time (about 5 seconds) While the engine is surging like this it is vibrating a good amount.. you can actually feel it shaking bad. anyone have any ideas of why it would do this?
