View Full Version : Cruise Control/Boost Problems

09-25-2009, 02:38 PM
So I replaced my headlight/cruise control stalk not to long ago and I have problems with the cruise control since. Sometimes when I hit the button cruise control won't engage, sometimes when I resume it the cruise control shuts off. Now today when I was on the highway and going up a hill the car would go from -10 vac to 5 psi and it would surge back in forth until I got to flat ground.
Could it be my n75 valve, throttle body, or my cruise control?
Also since I have installed my inlet pipe boost has been really weird. Please let me know with all my problems.
