Run away Idle on 85 Golf (GTI)

Jan 05, 2004 2 Replies

I have a 85 GTI with a 1.8L ,5 speed, stock engine with a terrible idle problem. As soon as the engine begins to warm up, the idle goes to 3500 rpm and stays there. I think it might be the cold start circuit but how do I check this. No one around here wants to try and solve my problem because the car cannot be "just hooked up" to a computer. Real mechanics are getting scarce. Any help or suggestions will be greatly appreciated.


The idle on my '87 was too high also, but not as high as yours. What type of fuel injection do you have? Do you have A/C?
