Engine Performance problem
1991 Chevy S-10 6 cyl Four Wheel Drive Automatic 150000 miles
when I get to 60 mph or so if the engine is under load it starts to hesitate. Will run ok if I let off the gas a bit. I first noticed it about a month ago pulling my boat. Then it went away. Now it is happening all of the time if I accelerate after I hit highway speed. I can punch it and downshift and it will still pick up speed but will hesitate the whole time. Feels like my outboard when I drop a cylinder. I changed the fuel filter and it didnt help. It seems to do it less if I run premium. Any ideas.
have the same problem?
