ok, my car is idle surging like a ****. it started off just doing it when it was cold, but now it does it all the time. its a mini me, z6 head on a y7 block. ive cleaned the ICV and checked all vac's but cant find out whats going on. help a brother out, and i'll give up my cars pictoral virginity on HT. clean EG

 

air in the coolant. or even fast idle vavle.

 

what do you mean by a fast idle valve? some other people have ben telling me a possible bad intake manifold gasket? do intake mani gaskets go out faster after using nitrous? hmm. i guess theres alot of possibilities. insert your 2 cents

 

Spray carb cleaner around your intake manifold to see if you have a leak. Post your findings when done. This will determine if you have a leak somewhere.

 

i would say fast idle thermo valve. do what this thread says and lemme know if that fixes it https://honda-tech.com/zerothread?id=699787
