Up until last summer it towed wonderfully , up hills no problem. But now that its getting older there doesn't seem to be as much power.
Its not the strain. Ours never lost power, and it had 160k on it when I sold it. A couple of thoughts on that. Clean the throttle body. These are notorious for getting gummed up and killing both mileage and power. If you are mechanically inclined it is easy to take apart and properly clean. Are you over 100k? If so change the plugs if you haven't. Only use what GM recommends. Some folks try to put performance plugs and cause themselves nothing but grief. Change your thermostat. They typically go bad at 100k. A bad thermostat can make it run a bit cold, which causes the PCM to make it run rich, which in turn can melt the inside of your catalytic convertor. Clogged CATs are very common on GMT360/370s between 75 and 120k. Symptoms are loss of power and using more gas, and they won't throw a code either. My CAT went bad at 110k. The only test for a CAT is a pressure test. Find a good shop that will work with you. Most never consider a bad CAT when there is loss of power on a Trailblazer/Envoy. Search for "catalytic convertor" on http://gmtnation.com/. A bad thermostat can also cause your engine to eat more gas.
