Check to see if there is a blockage in the exhaust system. Will the engine rpm go to 4-5 k in neutral? If it won't, there may be blockage. A 'back-pressure' test can be performed to check this too.

Have you tried plugging the old MAF back in ? Why did you replace it in the first place ?

Also have you tried checking the ECU for any diagnostic codes.

Fuel filter clogged or Throttle Positioner Switch needs adjustment (not coming off Idle Contacts).

The exhaust is totally unrelated to either of the bits Mick mentioned!
