My car used to fire right up when I hit the key when it was cold outside hot outside it didn't matter well when I did the upper intake delete and deleted the cold start it still started up perfect in the summer time but in the winter it was a little cold natured well now I've noticed over the past month or two it seems like it's a little extra cold-natured like it's a little longer to start and then like you said it it doesn't run very decent when it first starts it doesn't want to let me give it much gas but after it warms up is gone and I really used to think I had a miscarriage a slight little misfire but I began to think that's just have those cars ran because my 87 did the same thing but I thought it ran good but it had like a slight stutter is what I called it not quite even a misfire more like a slight stutter now that I just listened to this video while I was working I had to rewind it and watch it again and pay attention and I think this might be my issue right now because it runs good once it warms up but it just takes a little longer to start than it used to I almost want to make a video of a cold start when I get home and send to you just to see what you think I'm almost embarrassed to put it on my KZitem channel for the cold start LOL

XSDGX I run a Nistune Ecu. It didn't stop mine from starting. At least with the proper z31 tune. Ecu needs to see cas in order to trigger injectors and coil. Somethings not right if you have no injector pulse or spark. Usually faulty cas will cause this. Or a break in the harness. Test all the way back to the ecu and make sure everything is within specs. What if any DTC does Nistune show?

XSDGX plug the USB from the Nistune ecu into laptop. Turn key to on. Run Nistune software. Consult ecu through software. Click on F6 or Display consult gauges. In consult view lower right side says ecu messages. Any DTC will be listed there. If you need help let me know and I'll make a video for you on how.
