i have an 88 s10 4.3 4x4 tbi
Changed the oil,new plugs and new wires
Upon restart the idle was rough and after a min to rev back down to 1grand
It would bog down and putt out
The distributor is no more than 6 months old Did the wires one by one matching the next day
I Ordered a map sensor and an idle control valve and still the same problem
I dont thinks its a fuel issue cause i have an electric pump so it would just die
My wallet hurts and im stuck
Any suggestions???

 

Re-check your plug wires from distributor to plugs again. Odds are that is the problem.
