Need to ask some advice;

My sc is running rough and I have a fairly consistant "Check Engine" idiot light. The tach cuts out ocasionally but this have been normal for the 7 years I have had the car.

EECIII error codes are

157: Mass Air Flow meter below minimum voltage


212: Loss of Ignition Diagnostic Monitor inuput to EEC processor/SPOUT circuit grounded

Does this sound familiar to anyone?

What is the easiest way to correct it, New MAF?
What is a good MAF

P.S. I have a magnuson S port on it with the stock MAF and TB.

Thanks for any help.

The motor is consuming a bit of oil as of late and has 171K miles. So it is tired and probibly can't handle a big upgrade.
