Cleaned the Manifold now several codes keep popping up help

Gonna go out on a limb here -- you probably left a wiring connection undone. I believe you only needed to unplug the connector at the lower right of the throttle body in order to remove the IM. But I think the wiring harness has 3 connectors and you might have unplugged one of those other ones as well.

 

Hmm. Have you checked that all the hose clamps are tight? I recall that a couple those were easy to forget about sliding back into proper place and making sure that the clamp rings were tight.

 

Well if it was somehow a wiring issue, the repair manual should have a procedure for checking continuity of individual connections with a basic multimeter. (You don't really need the manual but it will show you what pins on the ECM connector go where.)

Low 12V battery is also known to cause misleading DTCs. But since you have recently had your hands on the MAP, MAF, TPS connections it seemed more likely to be the wiring harness connections to me....

 

You might be able to fix it with a tap and die set. Just be sure to thoroughly flush out the shavings.

 

You mean on the intake manifold itself? Might be a captured nut, not sure if it can even be removed from the plastic and replaced. The bolts at either end of the EGR pipe only get tightened to 10N-m which is not even 8 ft-lb. Don't let any gorillas under the hood...

Yeah, if that threaded insert is loose and spinning, the simple fix is if you can afford to replace the intake manifold.

If that's out of the question, well, there are suppliers of threaded inserts like that, and you could experiment with various sources of heat for getting the old one out of the manifold and somehow securing a new one in its place. Success would be far from guaranteed....
