K5 help

[no moa]

1987 K5 blazer, 350, tbi. 49k original miles. Been sitting for awhile, new coil, cap and rotor, distrib module. Plugs were ok.

Runs like crap at idle, stalls, runs ruff when its running. I put in a new battery, fuel tank is full with clean gas from a month ago.

Yesterday it idled and ran beautiful for about 10 minutes, i was inside the shop and i heard it stall. I went outside, fired it up, won't idle, and i now i have no throttle beyond about 1500, it just wants to cut out and stall. If i feather the pedal i can keep it going barely. Almost acts like a lost a bank of cylinders.

Any thoughts, gas seems to be good, it doesn't have that ethonal foul smell, injectors are firing. Any thoughts? Trying to get this running good so my father will finally use it. I hate to tow it to a garage and spend $90 and hour untill i've exhausted all my options.


Thanks in advance.
