I Have A 95 Blazer 4.3. Engine Seems To Run Ok, At Highway Speed Seems Like Holding Back. Abs Light And Engine Light Both Stay On?

Have you checked for codes since light is on?
Did abs and cel lights come on at same time?
Do you hear or feel any noise from brakes or wheel bearings?

Here is how to check for codes if not the OBDII system:

Jump terminal A & B with ignition switch off, once jumpered turn ignition switch to run without starting engine. Check engine light should flash, pause flash flash meaning code 12. Each code present will flash 3 times then move on to next code. Post codes.

Hope this helps

You might also check with your local auto parts store for a free diagnostic scan to get a code then like Tempfixit says, we can discuss it here.
