Sporaddic RPM problem? (SEARCHED)

[GoTRicEo0]

When I'm on light throttle, my RPM will stabilize under certain RPMs and start to bog.

I noticed in 1st gear it stops at 4K, 2nd and 3rd stop at 3K, 4th and 5th stop at 2.5K. My SAFC II reads AFR at 20.x:1 sometimes even 30.x:1 during light throttle. Punching the gas does not help either.

This may also be off topic, but my temp gauge does not work either.

I played with the MAF and I noticed the connections were loose. I repaired the connection but it still does the same thing.

I have a feeling its a sensor issue or possibly a boost leak. I have no access to a voltmeter and my tools are very limited. I have yet to check for codes but I will when I get the chance.

Anybody have any sort of idea on what it might be?

well, I tried to narrow down the problem and unplug one sensor at a time and drive. Nada.

Pulling codes atm.

While Pulling for codes, I noticed one thing. My ECU doesn't have an LED. Then... I saw adrian's old post on how to use an AFC or something like that hahaha. Installed the Z32 maf and running better then ever.

All in all, problem was a bad maf :[-Jeff
