Hey guys long time no talk...I got everything I had ordered into my stang now im having some troubleshooting issues. I am having trouble idling after she is hot. When cold I start her up and everything is ok and then like I said Ill shut it down and then go to start it up again I have to keep my foot on the gas to keep her goin. I adjusted the tps and its right where it should be .98 but the problem is persisting. Would a adjustable fuel pressure reg do the trick? Any other suggestions? Thanks in advance!
did you disconnect the battery when you changed t.b?may need to set base idle, then t.p.s voltage.a bigger t.b will cause a lean condition. an adjustable f.p reg. would be a good idea. along with a f.p gauge
did you dissconnect the battery when replacing t.b? you will have to set the i.a.c and base idle. then check t.p.s voltage.a bigger t.b will cause some lean issues. so an adjustable one and a gauge would be good also.
I had the same problem starting up when hot. The idle would go down and up for a second a die. I performed a base idle reset and it idles perfect at 750rpms now.
