ive got a 1992 civic hatchback with a greddy turbo kit, and it just recentley started getting cold outside... i dont know if this relates to my problem in any way but when i turn the car on it runs fine, but after a little while it revs high then low, high then low, repeatedly. this also happens when im on the clutch at a light or something. after a little research i think it might be the ICM (igniters) but i really dont know much about cars so i just wanted to get a firm answer before i spend my money
