87 K5 TBI running issue
I recently got a 1987 K5 with a 350 TBI. It was running ok but had an intermittent problem of having no power on acceleration. After checking timing and seeing it was off I reset it to spec and also installed a new fuel pump. The truck ran great cold which it never has but once it got warmed up it started missing and had no power. Any suggestions?

i dont know if this truck is too old to have this issue. but have ran into this problem with 90-91 chevy tbi engines, probably the same thing. anyways the temp sensors would go bad and get stuck at like -35 degrees. so it makes the vehicle run rich as it thinks its freezing outside. unless you have a scanner to check that dont really know how to diagnose it.
