Why are my RPMs so high but the speed/power so low?
I have a 2000 S10, 4.3l V6, 133000 miles, and just recently when I press the accelerator
the RPMs sky rocket, sometimes to 4500, but the gain in speed is very slow. Going up
hills is also a problem as I have to keep the RPMs very high just to maintain current
speed. It starts and idles perfectly, I just don't have any power.
The last repair I made was to replace the water pump about 5 years ago. Other than that
it has just been routine maintenance.
