Hey all, I have an 86 S10 2WD w/2.5<br>4 cylinder $ EFI. It has an erratic<br>idle that's on the high side and it<br>races a lot. When I give it a quick<br>stomp it'll drop down to a lower rpm<br>that is still a little too high. I suspected<br>a vacuum leak but can't find one. Thanks<br>for any help.<br>4LOW
