Engine power loss

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.

2002 chevy impala has loss of power. will not go


I would look into the catalytic converter too. I just went through this same symptoms. The engine will sputter and run rough. Drive a few miles at night and see if the front exhaust pipe, right behind the radiator, is glowing. That keyed me in. There is a special service to fix certain models for 01 and 02 which is sort of a recall but not exactly. The dealer just fixed it for free. The chevy customer service number is 1-800-630-2438, they can check and see if you Vin number is on the recall. Your local dealer may not know about it so call the number first and make sure you have the Vin, at least the last 8 of it, when you call.

Engine turns off when coming to a stop


I have used this procedure for years.
Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
