Did you damage the maff ?
Have you swapped the maff housing as this can alter the readings the maff gives and will cause these types of issues.

Sounds like you could have a problem with your Mass Airflow Sensor - it sits in the intake pipe. Have you connected it all back up correctly

Can't remember how many wires but it's a long flat plug on top of the inlet housing

Out of curiosity, have u pushed the new filter onto the pipe too much? If this is the case you are starving the engine of air and therefore it wont run and youll have the symptoms described. best to take filter off but leave maf connected to see if itl run, if not its the maf.
