"JUST ONE OF THOSE THINGS" God how I love that saying cause Ive said it about my "High Idle" sometimes sitrep, screw it.
And to ad this, I bought ACDelco MAF sensor because I thought it would have been made in the USA, but when I got it, sure enough, made in CHINA, so I sent the dam thing back just on principle Really showed them huh

Hahaha! The delco parts I got came from different areas. The fuel pump came from Brazil, and the o2 sensor came straight from Japan. (JDM spec GMT400 now? XD)

Did you ever figure out your miss at idle?

Having the exact same issues u got. Including the slight suction at one tailpipe, and did everything u did except change fuel pump...
