Hey guys everytime i start my R33 series 2 up after about 4-5 mins the car starts to rev up and down roughly about 3-4 mm this usually stays like this till the car is completely warm after driving for like 20mins.
The mods on the car are a Greddy FMIC, Apexi Pod, Apexi cat back exhaust, Just jap dump pipe and high flow cat.
Looking for some sort of help from people that have had this problem and got it fixed or a professional i can come see to get the car look at. I live in the eastern suburbs so if someone knows a good business in that area willing to go get it checked out.
Cheers guys
Chris
