Experienced the same thing with my chevy s10 2wd pickup. Ran fine on the flat, but as soon as I went up a hill or the side of a mountain, I lost all power, and the truck just bogged down so bad that it was embarrassing. Once I crest the hill or mountain side, the truck runs great...problem solved, cracked exhaust manifold. GOOD LUCK. getting the daggone thing off...the bottom two bolts are impossible to get to.

First check for any cracked pipes leading into the intake manifold If all OK (with no codes showing it probably is OK) try checking the fuel pressure regulator. If you smell fuel from the pressure regulator vacuum side arm (when the vacuum line has been disconnected) it needs to be replaced.

Check intake gaskets. Pour warm soapy water on the gasket when it's running. If it bubbles like crazy, you have a leak. 2. Check timing. Shoot a timing light at the crank mark. If it jumps around a lot, your chain has jumped. #3. check cam. Remove valve covers, run the engine, and see if they are all raisng the valves the same. Put a piece of cardboard along the bottom, and fold it around a little, so it forms kind of a " half valve cover". That way you won't lose oil everywhere, and make a mess, or a fire.

Car won't pick up speed on acceleration


You're not getting enough fuel. You should check your fuel pressure. If you have enough fuel pressure, your injectors are probably clogged up. Run a lot of fuel cleaner through your tank when you put gas in and see if it makes any difference. Lucas fuel treatment is the best to use.

There is no shut off switch on a 2002 chevy S10. Sorry for the bad news.
Good luck and hope this helps, there is a fuel pump relay in the glove box behind a rear panel to the left corner in the box. The relay i believe is the middle one of the three.
