I have a 1992 Chevy S-10 Blazer 4wd auto, with a 4.3l Vortec V6. It has a
new fuel pump, filter, spark plugs, plug wires, rotor, cap and computer.
It has also had the cat converter cut off. The timing has been checked and
is dead on. The problem is, it has no power at highway speeds. It will
roast the tires off sitting still doing a power stall. But going down the
highway it will only get up to 65 mph with my foot on the floor and any
little hill will make it pull down to 45 - 50 mph. It was hooked up to a
computer for diagnosis and it showed nothing wrong.
I am willing to listen to any comments. Please HELP!!! Thanks.
