CausesA code P0102 may mean that one or more of the following has happened:

The MAF may be disconnected, or a wiring connection may be bad
The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF).
The MAF sensor may be faulty
The vehicle computer may be faulty (very rare)
Possible SolutionsThe simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:

Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
Inspect for any air leaks near the MAF sensor.
Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
Replace the MAF sensor.

Do you have any oil in your cold pipes? It could be a bad seal or just too much oil on your K&N style air filter. I'd grab some TB spray clearner and give the MAF a good cleaning. If that doesn't work, try swapping it out with another MAF from a good running truck.

No oil watsoever already did the maf swap I had extended the maf wires along time ago could that b it?

That's exactly it , it's an open wire in between the maf terminals and pcm terminals. May or may not be your splicing, but GM wiring is known to have open and corroded terminals on that connector and the throttle body.

Best solution and quickest, is to replace the three wires with new ones.
It'll fix it.
