I Recently purchased a 2000 S10 with 85000 miles, 4.3 with automatic transmission, 2WD. It had a slight hesitation around 55 mph so I added fuel injector cleaner, dry gas, changed plug wires, distributor cap, and rotor. It still has little power, it idles but will not accelerate. How do you get to the plugs to change them and what else could it be? How would I check the muffler and or cataylic converter?Ran well for 2 weeks, ran approx 60 miles on this full tank of gas. Any ideas are greatly appreciated.

Have the spark plugs been properly gapped. Also could need youre fuel filter changed. Also could have a weak throttle position sensor (TPS). Could even need a youre fuel pressure tested, Also Fuel regulator is weak also.

Good Luck.
