The blazer ran well, but then would not go over 60mph when on the road. Now wont hardly get any power, Has all new parts including a bebuilt trans., problem existed before trans exchange. Can you tell me what may be the problem. other information states that it is not the ingine or the trans.. but something plugged up,, can you give me some idea as to wht is wrong?

did you also check for correct timing. as for vacuum lines, just look around and see if there is any disconnected. you should hear a hissing noiseif there is one disconnected. you may also wanna check and see if you have a bad cat converter

you can either see if there is pressure at the tail pipe, or with a temp gun see if there is a temp change at the input and output of the cat converter.
