So im still having the COLD start up problem..here is an update i fixed A fpr leak. cleaned the maf, the aic, and changed the tps sensor and reset. Even though ive done all this my car still dies out.

I ran the codes this was my result.

Instead of blurting out an answer that you said you fixed I did some research on what you identified was a problem hope this helps bro
From what I can see your o2's are messages up or unplugged

so my o2 sensors can give me start up probelms and only when cold though??? Because when it reaches normal tempatures it runs fine.

Could be something to do with open loop vs closed loop

I had this same problem in my last coupe. Try restabbing the dizzy and doing TDC. My dizzy had a lot of play in the shaft. I replaced it and re-stabbed the dizzy at TDC, and it fixed my cold start issue
