Question about 1993 Chevrolet S-10
93 s10 4.3l losing power only when driving and the colder it gets the worse, but when it is park the engine can rev up perfect. trying to get on highway was a disaster, wouldnt get up yo 55. got code 35 (idle air control) and 44 (O2 sensor), i changed both and get same codes and didnt change the power loss
Hi. I would try changing the fuel filter. If its partially plugged up you could be starving for gas and that can make your emmission sensors give bad readings. Cant gurentee it, but it would be a place to start.
