1987 K5 problem...
I bought this truck last year. 2 days after my purchased the engine blew. so I replaced it with a 350 5.7L TBI. since I have had a problem with it missing while its running and at a idle. and dies with out any sign. it just shuts off. I have replaced all vacuum lines, distributor, all sensors, rebuilt the throttle body and it still is happening. only thing I think it could be is something is screwy in the harness. giving a real thought to switching to a 650 holley carb. I have gotten all my info for these boards so I figured y'all are the best to ask!
