How rusty is this truck? It might be a corroded/bad ground.... I had an 89 S10 in NY that wouldn't idle... it would almost stall, rev up, go back down and almost stall again. I also had a surge at speed and an intermitant loss of power. The problems all stemmed from corroded ground to the ECM. I also had several other bad grounds... the one to the neg. battery cable was so bad the wire wasn't even copper anymore... so, you may want to check the grounds.
