HELP! Code PO103

I was putting in some replacement wal-mart fogs, and installing a newer (not rusty) filter on my CAI, and my car is throwing a PO103 code (according to the scanguage).

Car sounds like **** and idle's horribly.

I've disconnected the battery, re-connected the battery mumerous times, and re-tightened all of the hinges on my CAI.

Any input?

Re: HELP! Code PO103

Go to auto parts store and buy MAF Sensor cleaner. [follow directions on can]

How long ago did you oil the filter? It should have had time to completely dry before being reinstalled. Otherwise, you are just coating your MAF and Intake with oil.

Re: HELP! Code PO103

Latest Update: We reset the ECU, and turned the key to the ON position (without turning the engine) and it still popped the code.

Unlikely, because the MAF is reading too much air.

Re: HELP! Code PO103

OK, it's the sensor, but the code is present even before starting the car. So I'm thinking a wire was pulled out somewhere in the MAF sensor wiring harness when I was dickin' around in the engine bay. Is that even something you can buy?
OR am I screwed and have to take this to a dealer...

Also, is there a PDF or something that can tell me what the voltage of all the wires is suppsed to be? Cause if it's just one wire, I might be able to fix that.

*this sounds like domething thomas could come up with*

Re: HELP! Code PO103

Look into the connector to see if all the pins are on the same level. It's pretty hard to dislocate them by accident, though. The MAF could've been damaged by overoiling the air filter, def try to clean the sensor first.

Picked up some maf cleaner @ autozone.
Cleaned it, reset the ECU, plugged it back in. Same problems.
Repeated cleaning and reset again.
No luck.

The only thing I can think is the wires from my MAF to my CAI were fairly taught... maybe a single wire came unplugged?

I don't want to take it to the dealer if I don't have to, last time I had wiring issues, I took it there for a "full diagnostic", and they charged me 97 dollars and quoted me the codes. I figured out what it was myself and fixed it for virtually nothing and 30 minutes of work.

So.... yeah. I think I'm up **** creek.
Car won't go over 3k rpms w/o bogging.

Re: HELP! Code PO103

Any chance there is water in the connector?
Factory manual for the P0103 advises to theck for open in any 3 of the VG, E2G and +B circuits or a short in +B or VG.
Another possible cause is the ECM.
If the wiring brakes that usually happens near the connector. Sometimes you can even feel or notice it through the insulation. Black, Violet and Pink are the 3 wires.
