Loss of power on 95 Blazer 4.3L
Hello,
There is a problem on my Blazer now, it miss power ! The V6 roars, the transmissions works good, but no power...
Engine light is OFF.
I don't know where it could come from. Does anybody had a similar problem here ?

when my fuel pressure regulator started leaking i had very poor power, i also got 10mpg and black smoked real good at start-up. Usually a clogged cat wont let the engine rev high, i say usually just becasue there are always exceptions.

I had a similar issues on my 98 s-10 pickup the cat clogged up so bad even downshifting and flooring it the truck would barely move. So I unbolted the cat and started it up and ran fine so I knew it was the cat . Without exhaust flow it won't run.

I've dismantled the exhaust today. This is what there was inside the cata !
Some of these blocks of ceramic were inside the muffler... I think this is the cause of my loss of power.
I'm gonna do some welding... and put the empty cat on the car...

I've tried with the sensor on and out the exhaust, it's almost the same. And no CEL. It just miss torque because my cat is empty.
I've tested my emissions on a gas analyser, the lambda is good , 1.02 .
