ls10blazer1995

I have a 95 blazer with a 02 5.3 with matching 4l60e. The problem is i got a p0101 code the other day ran perfectly fine b4 that code. So i bought a new mas air flow didnt fix it. come to find out my cai i had a 90 elbow right before the maf took it off and the code went away. Now what the truck is doing is now the acceleration is sluggish. It feels like im towing a trailer. But it will turn the rpm to red line like it suppose too, just feels like a full trailer is behind the truck. Tryed a new maf nothing changes. Truck is stock beside header, exhaust, and cold air intake. And b4 that code the truck would bun the tires down now nothing. I just need some idea of what it is. Thank for your help

What did you put in place of the elbow?
Nothing?? If so, there's a chance the MAF is getting whacked by turbulent air, and is reporting phony info to the PCM....
