My 1990 GTU (GLX) is starting up but its not leveling the idle out, Instead if the MAF AFM sensor is unplugged on the replace for the air box with K&N filter it starts and revs up but when u let go of the flapper inside the maf afm the car dies if u plug it in and let it go it dies... I ordered a short ram air intake for the car but if i do that do i have to disable the MAF AFM in the computer?

please help,
