sigh.. CEL

[stateofidleness]

it's back!

car running fine for quite some time (since last post) with no CEL (only thing is it seems like the idle might be high at startup, 1k)

driving to school like normal today and raced a yellow light
when i stepped on it (read, accelerated real fast) about a minute later, the solid CEL came on... I haven't had a chance to read the codes yet, but I will when I get out of class

again, I started scouring the net for symptoms.. I have a pre-existing exhaust leak that is "minor" but should be noted. Is there any way to "bench test" an MAF? mine looked brand new when taken out to inspect, so I'd hate to replace a good one..

also, my mechanic has offered to smoke the exhaust system and attempt to fix the leak.. what does it cost to have this 'smoking' done?

thanks!

EDIT: I should note that the AOS was replaced since last post as well. Wasn't sure if I mentioned it. No smoke is present now.
