Hey everyone, I am completely lost as to what to do. I changed a wheel bearing on the G and took it on a cruise on friday it drove perfect with no issues although the weather was terrible and super slushy out. On sunday i went to start the g and it didnt want to idle well it was surging then almost dying i shut it off and started it again, it died almost instantly, the next time I started it It didnt want to idle well but i decided to try to go around the block to see if it would drive the car wouldnt rev past 2k rpm and it almost felt like it was hitting the limiter at 2k. I brought it back and pulled the codes.

The codes I got were P0101 Maf circuit performance malfunction, P0113 Intake air temperature circuit high and P1136 intake valve timing control solenoid valve circuit bank 2.

A couple weeks ago at my buddies place we used his super expensive reader and it showed a code for abnormal battery voltage he didnt know what to make of it.
I have recently removed both the maf sensor and the vct solenoid on bank two and cleaned them but didnt have issues until right now that was two weeks ago, I think its probably a wiring issue or a grounding issue I had also been driving the car for a couple weeks in snow without fender liners so my engine bay is really dirty but i put the fender liners on a few weeks back and i dont have the sttock under engine cover on but an aluminum under shield it doesnt cover everything the stock one does but its close i have no idea where to start does anyone have any ideas? help would be greatly appreciated.

also looking at the pins on my maf sensor connector and the last pin slot doesnt have a visible contact like the rest is that how they are? or is mine missing a contact?

 

Chances are pretty good that you got water in your delicate electronics since you drove around in the slush without the protective covers.

Those things aren't to keep mud off the engine, they're to protect wiring, prevent water from getting into electronics, etc. Absolutely VITAL that you not drive around with them removed on any modern vehicles.

The 6 wire harness only uses 5 of the wires, MAF uses pins 2,3,4. IAT uses pins 5,6. So yes it's completely normal for pin 1 to not have wires on it.

I would start by replacing the MAF, sounds like something crapastrophically failed on either it or the IAT (part of the MAF sensor).

The P1136 could be caused by the MAF failing, usually you will get a cascade of other codes when one item fails.
