2002 and 2003 std swaps
When i go to start the car after it has sat for a night it will crank and crank. hard to start. double glow put my foot on the throttle a little bit fires right up. its runs rough though, like the IQ is off and its shuddering but i have played with the IQ and no difference. timing is dead on. i played with channel 5 on vcds but havent seen a difference. even when its warm it has a little trouble starting. but when I apply a little throttle fires right up everytime. I am lost. once it warms up a bit the thing runs like a top idles fine does everything its suppose to. the car used to be auto and previously to standard swapping it, it would fire up everytime no trouble. not my first std swap either.
