1995 Tahoe rough idle won't run
I have a 1995 Tahoe I just swapped motors in. Before installing the new motor; which
is out of a 1992 Chevy truck, I went through and put a new tune up in it. Plugs, wires,
cap & rotor, egr valve, oil and water pumps. Once I got it timed it ran ok. I was able to
drive it across town and back to where I did the swap. After shutting it off when I got
there it started to run crappy. I'd pull up to a stop sign and it would die. The first time it
took almost 10 mins to fire back up then I'd put it into neutral to keep it running. It died
again so I figured it was out of fuel. Still not the problem. While trying to time it at first
it was 180 off and backfired through the tbi twice and once through the exhaust. Made
it home and can't get it to start now. I haven't checked any codes yet as I just got it
home today (11/9/2014)Any help is appreciated.
