Major no power issue
92 2wd blazer, Vortec injection.....Truck runs fine, not missing but just wont pull at all, very slow to rev.
It acts as if the convertor is clogged, but its been removed and exhaust is flowing very well 100% sure.
I checked the fuel preasure and it holds 50 to 60 lbs.
Spider injector was replaced 2 or 3 months ago.
The check engine light is not on, I checked codes and it throwed me 43 which is knock sensor.
Im at a loss..............
Open to suggestions.
What the hell is wrong with the blazer???
Im pretty good with engines, built a few and work on my own stuff....this thing belongs to my daughter, Ive never fooled with a vortec and I think the problem lies there ( But Im not sure).
THANKS !!

After checking and cleaning IAC and EGR, no change !!
HELP !!
Just for the record. the IAC is idle control, if its bad...it wont idle, otherwise will run just fine.
Cleaning the EGR offered no power gain at all.
