hesitation when at driving temp

[nismo300zx1990]

Ok so I am hoping that someone has had this issue because I have been trying to find out what is the problem for three weeks now.
the only code I have showing is 35 which is the egr gas temp but, I have deleted the egr valve and I have not had this issue before until now. It all started one day when I was driving home and it stated I looked around and found out that my started wire had gotten on my header and melted it. So I assumed that was the problem and fixed it, but the problem still exist. any help would be appreciated.

Must have also damaged the wiring for your coolant temp sensor or IACV would be my first guess. If so, good luck cuz i would expect it to be a pain to try and track that wiring back to find the burnt spot but you might have to tackle it.
