Well set the timing to ten and it idle but at like 1900 and adjusted the screw and it's goes from like 1500 to 600 with a flick of the wrist. Well I let it warm up and tried to go for a drive and it started to run bad and just died. Sprayed all vacuum lines down with carb cleaner and no increase in idle so vac is good. Spark is decent. Fuel pressure is average. What's next

Have you pulled codes yet ? With it dying all the time, you'd think the computer would have stored a couple that might help point to the problem.
As for the idle, a "Base Idle Reset" might be in order.
And that's only if your 100% sure there's no vacuum leak.

Sure, just search this forum or Google it. You'll find step by step instructions on how to do both.
Report back with what you find.

I'd clear the codes, do a base idle reset to see if that helps the TPS codes, then drive it normally for an hour. Then pull codes again to see what's going on.
That Error code 15 has me worried though. That's the internal chip in the computer saying something is wrong with the computer itself. Hopefully that one doesn't come back.
