5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
Well i timed it and holy crap it was way off. I have it timed at 12° now but there is still the miss. I think its because there is too much fuel pressure. Its at 42-45 on idle. I got that bbk regulator before realizing they are junk.
I had a BBK fpr on my 90, I didn't have any trouble with it.
Yea, i put the stock one back on and still have the same issues. When at idle and cruise it misses bad but once you floor it, it wakes right up and doesnt miss at all
Ok so wow i feel like a f-ing retard. I was looking over everything and i noticed that the vacuum hose to the map sensor on the firewall wasnt hooked up. I hooked it up to a vacuum port and the rpms shot streight to 3k it wasnt missing thou and no smoke came out. It sounded pretty healthly but my prob now is that its stuck at 3k rpms. Is it cause the cam is so much bigger so the computer is reading less vacuum?

if you don't have a maf conversion, the oem speed density will not run right as load calculations/fuel map will be skewed as map is a contributor for such based on vaccum readings as for idle, perform base idle reset.
