P0102 Code MAF or VAF Circuit Low Input

When the engine is cold the idle oscillates between 700 and 1300 rpms.
When it warms up, idles at 1200 in park.
Shifts too soon, really fast and hard, (short shifts).

Tester gave me two errors:

P0102 MAF or VAF Cicuit Low
P0102P

Any ideas?

Make sure the airfilter isn't sucked up into the MAF. Try running it shortly without the airfilter in. Unplug the MAF and see how it runs. Tapping the sensor with a screwdriver handle can sometimes make the sensor respond or make the engine run different. If the airfilter doesn't do anything it is probably the MAF.
