87 3sfe High Idle

[GT_Copeland]

Im new to toyota! i just got a 87 celica for $500. Anyway it runs at 2000 rpm's for an idle, could a valve adjustment be a possible problem? Also where is the best place to find some performance parts for this thing? Would like cams, headers, pistons......?

Does the idle always stay at 2000rpm? Or does it slowly drop down to ~800-ish as the car warms up?

Common problem with Toyota EFI engines in the 80s and 90s is an air pocket/bubble in the cooling system which tricks the idle speed control valve into thinking that the engine is always cold, and thus keeps the cold idle valve open (hence the high idle). If the idle speed doesn't come down when the car warms up, then bleed the cooling system to get rid of any bubbles/pockets and then re-check the idle.

On 3sfe engine the air bubble in cooling system has no efect on idle speed control
