We've recently just put in my new throttle body 68mm and now when we start the car, it has definate trouble and idles 500ish RPM (mostly in the winter time). In order to start it, I need to twist the key, hit the gas just a bit, and rev it at about 1k for a minute or so in order for it not to kill. We've adjusted the cable and it still has a rough time starting up. But when the car gets a little warmer, it starts to idle normally and runs perfectly fine. WTFMATE. Help a noob out! Thanks.
