well uhh.. i dont know much about my supra. i am more of a honda guy, but i got this supra for free so yea i just wanted to fix it up. and how much would it be for me to take it to a mechanic to check up on it?

well Diagnostic at any shop is gunna fall in the $55-75 range. But for starters you can try some of the suggestions stated here.. like testing the resistance with an OHM meter on your Mass Air Flow meter.

yeah I'm pretty sure your right... wasn't thinking that clearly also didn't think that when measuring resistance you don't have to have the source plugged in.
