Thanks for the videos , very nice. Tip for japanese philips screws, they need a japanese style screw driver which most people don't have. But if you give your screw drive a few taps with a hammer on the screw, they pop loose. What also works is using a plier to twist them loose.
So I've had a problem that seems like what your explaining when I start my car it takes a few tries and once it starts I have to hold on the gas or else it dies but once warm it idles fine is that what you experienced
I'm having those issues with my NA 88 everything in the fule system has been changed except pump. It went away for three a few months then came back. It will have a really hard time starting then do that hesitation on acceleration. My o2 sensor has been deleted so it could be that to.
