I just got my FC 65mm TB installed this morning. I have screwed around with the idle screw to try and get it right, but no matter what I do, the gas pedal is very hard. I never stall my car, but since I have installed the TB, I have twice stalled, and over a dozen times almost stalled it. No matter what I do or try, the pedal is very hard. It revs really high, once I do push it down, and I feel like an ass, cause when I am at a red light, it sounds like I am giving it way too much gas when letting off the clutch. But if I try to lightly push the gas and let off the clutch, it damn near stalls, until I push harder, that's when it revs real high. Does anybody know what the problem is? Does anybody know how I can solve this problem? I have a 2000 ZX3 Manual.
