hi, i am new to this forum as i just recently bought a 89 accord (i am only 15)
well it starts fine then it seems to idle at about 1,500rpm then gradely moves to 2,000rpm
and idles there, the car is a project car and i really need to figure this out before i start on other things and also u can hear it sucking in air when its idling
after u rev the car and it goes back to idle it makes a weird noise coming from around the plenum <<< not to sure on spelling
any help would be appreciated thanks

Is it a carb? If so, is the car warmed up? These carbs idle high until the engine is up to operating temps.

You can use carb cleaner. Spray it on the lines and the engine will act differently if you sprayed the cleaner on a leak.

yeh i found them thanks mate, umm i think the car is missing the air cleaner, and the vacume hose from the idle controll solanoid valve has a bolt in it, could this be the problem ?

Probably. It's a cheap enough first step.
