I've done a bunch of work to the truck and its still running like crap.

I was poking around on the AutoZone website and noticed the 2.5 calls for a different plug then the 2.3.
The only real difference is the stroke of the engine(different crank), I'm still using the 2.3 ECU and accessories, but could the plugs really make that big of a difference?

I'm running Autolite iridium plugs, the part number the 2.3 calls for, not the 2.5.
Again, I'm using the 2.3 ECU and accessories, with the 2.5 longblock.

Edit: I haven't been getting any codes except the nagging 1443 code, I also replaced all of the ground wires including the main ground that goes to the engine.
