Code 33 is basically a plausibility error for the MAF. Too much flow to be plausible based upon other conditions.
Flow > 45 gm/sec, with throttle < 14.8% and rpm under 3200 for 600 ms can set the fault.
You may want to clear the fault from memory by disconnecting the battery and see if it re-occurs.

Where are you from, belzileb? Can you fill out your profile for us?
Now, you say you had a code 33 and you disconnected the battery and the code reappeared? And you have swapped MAF and same problem? Did you disconnect the battery after the MAF swap?
Do you have a FSM (factory service manual)? You can follow the troubleshooting steps for Code 33.
