Re: 96 s10 4.3 vortec high idle please help
Yes very common and annoying symptom the 4.3's have with the 5spd. For me I just try to keep my throttlebody, MAF, TPS, and IAC all very clean. I try to clean all these up often and then disconnect the battery to reset them all after you have cleaned them. This seems to help, but what helped mine the most and now it pretty much is completely gone is I had my tuner make some idle air flow adjustments and it acts much better now.
