Or perhaps buy the brand new original Bosch MAF from ******** for $177?

If it doesn't solve the problem, sell the MAF on eBay for $200.

PS. When you fit a new MAF, disconnect the battery for about 30 minutes to reset the engine computer settings to factory default.

Then, fit the new MAF and run the car for about 10 minutes at idle until it is running smoothly. Take the car for a run increasing RPM until maximum is achieved. This will allow the engine computer adapt the settings to the new MAF.
