sigh.. CEL

[stateofidleness]

flat surface when parked and Tiptronic trans. I might try cold-starting it with the engine cover off and viewing it topside to see if I can better place the source of the noise. Wouldn't I hear the noise on warm starts too though if it was the engine mounts?

seen a lot of posts recently about engine mounts so I was getting curious about mine.. I might try to get a "look" at them if it is even possible without dismantling stuff.

Again, I had more or less the same problems. The new O2 sensors fixed everything. I actually could not believe how much the computer relies on their readings for the air fuel mixture. If they are bad they also throw other electronics out and cause multiple error codes.

Try changing them and see what happens.

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.
