Any help to solve the problem with my Blazer will be greatly appreciated. Here's the story. I have a 1993 4Dr. S10 Blazer 4.3L Vortec , VIN code "W", with only 74,000 original miles on it. It was running rough and had NO power a while back since it had never had a tune-up. I did a tune-up on it (which included a new O2 sensor, plugs, wires, rotor and cap). I also put new exhaust on it which I had wanted to do for a long time. I chopped the cat off of it (opps :-) and put 2.5" exhaust all the way back with a Hooker Racing muffler. It sounds very nice, but it still ran a little rough and had NO power. So, I replaced the MAP sensor, which I had conflicting reports from 2 different parts stores on which one to use, and I replaced the throttle position sensor. Still no power. I know these engines have a lot of power. I had one just like it before, and this thing will hardly climb any hill, not to mention it takes all day to get up to speed on the highway. It has no power at all but it runs and idles great. I also had someone run a computer scan on it and everything checked out fine. It was also suggested that I reset the computer by disconnecting the battery over night, which I did for apparently no reason... does anyone have any idea what could be wrong? I'm completely lost, I don't know what to do next and I just want my Blazer to be normal again..
