hey. first off, im new. i have a 1990 eclise gs turbo. the problem is, it wont hold a steady idle. when you rev it up to 2000 rpms or more and try to hold it, it revs up then cuts out. it wont stay there. i have replaced the plugs, wires, fuel filter, ignition control mod, coil pak, air flow meter, and cleaned the injectors. nothing works. any suggestions?

 

Have you checked all vacuum hoses for leaks, cracks, or breaks?

 

usually it will have to do with the ISC motor but i would start with the vacuum lines. Also check out www.vfaq.com for a write-up on the fluctuating idle faq
