Chevy S10 4.3 4wd Startup issues
The engine starts right up when its cold, runs for about five minutes and then
wont idle, i recently changed the coolant sensor it seems to run ruff once it
My s15 did similar when it had moisture in the distributor...worth a quick look under the cap, dry thoroughly, clean contacts if necessary, replace rotor & condenser if they need it...mine had a cracked cap that was replaced as was the whole distributor shaft & everything ...yours could b just a bit of moisture there.
