Question about 2002 Chevrolet S-10
2002 chevy s10 with 4.3L engine. 5 spd manual. 125000 miles.
starts great, idles great, but when driving at any speed; it seems to bog or have engine power loss. can have the pedal to the floor in 5th gear and barely reach 60 mph. when i start up a grade, speed starts to drop. i've also noticed a miss (or minor ****) when trying to give it more gas for power. plus i hear a hissing sound when i get on the gas pedal. doesn't really sound like it is comining from under the hood, but more like under the body sort of in the center.

Throttle Body Cleaning on vehicles without electronic throttle control (most 2003 and down)
You can in most cases repair this slow speed stall or unstable idle by cleaning the engine throttle valve and the idle speed control valve using a product called CRC Spray Throttle valve cleaner. Spray the cleaner into the air intake of the engine with the hose removed from the throttle body, the engine will try to stall so hold up the idle speed manually. Once you have used up about 1/2 can of the cleaner stall the engine out while spraying and turn the key off, disconnect the negative battery cable for 5 minutes and then reconnect and drive the car for a about 25 miles of varied driving modes. If this doesn't cure the problem you may need the fuel injectors professionally cleaned by the dealer service dept.
