I got a match?? Thottle switch? I had an s-10 once and it was a 1994. The best thing I did to that truck was trade it.

take it to any shop, goodyear, firestone, whatnot. have a throttle body cleaning done. and not just a spray-that-shit-through one. a whole, vacuum, draw and feed through every goddamn whole in the tb one. shouldnt cost more than a hundred bucks. or just get rid of it

CPI eh? Clogged cat? Checked the Fuel pressure regulator or O2 sensor were the first things that come to mind before getting into other stuff perhaps.

The 94 and 95 S10s came out with the CPI (center point injection) which is notorious for causing problems :mad: , my truck was having the exact same problems last week and i got it fixed by replacing the cpi injection
