Yes it is A MAF Problem. Replace the unit. There are plenty options. 300zx, Q45, you may have to rewire and may need software like a Pwr FC. I have a Pwr FC with a Q45 unit. Works Great.

ABS Module should be in booth of car on shelf to the right of the batt etc.
I have read somewhere that you can do diag from the controler much the same as the ecm with the LED or Chk Eng lamp.
I am having an ABS lamp on now, also from locking my wheels in the loose.
I am about to remove my module to see if the diag can be done. will post the results.

Hi.
The Boost Control valve is pin #25 on the ECU. The Map sensor reads boost/vaccum for the gauge. I do not see any terminals for the map sensor on the ECU pinout.
