Im guessing its a 240, but what year?
Check the intake and air filter, make sure nothing is clogged. Check the throttle body, you may have to clean that. Also, the AIV may be clogged and sending exhaust into your intake, so check that out too.
Also don't overlook the basics (plugs, wires, distributor, etc) I would check the MAF too.
Mine was idling up to around 3000 a couple days ago and I just cleaned the throttle body and it fixed it all up.
