Engine idle loops

I have a 1990 eclipse gs-turbo and my engine loops when its sitting at idle. Some have suggested that it could be the EGR valve, fuel injectors, or the fuel pump. Does anyone have any suggestions on what it might be.

Could be clogged injectors, clogged catalytic converter...the list could go on and on. it's hard to tell without looking at the car.:(

first thing u should try is changing u sparkplugz.

had the same on my 91, change plugs reset the ecu. if that doesnt fix it then take some wd 40 and spray around the throttle body if u here teh rev jump then replace the seal.
