My main goal is to pass the smog test.
As for the mechanic, he's a good kid who's studying to be a mechanic. Seems to know his stuff. Found him on craigslist and he came out to me to work on the car. I interviewed like 6-8 others, and he seemed to be the best. He's diligent, and spent like 7 hours on the car diagnosing, working and cleaning parts. Charged me very minimal so far.
He's not trying to sell any parts since he just works on the car in the parking lot. He went through a kind of flowchart he got from that "All Data" thing (
http://www.alldata.com/), and was cool since he informed me that it even existed.
At one point he had me hold the gas petal while in park to 4000 RPM for 3 minutes. Then he tested the temp of something and he said it was bad because of I think a reading on the voltmeter - too high resistance or something. I'll have to ask him to find the exact reason. And I've emailed him a link below to verify.

it's easy to throw parts at car, especially ones he makes most money on, so be careful.
on a side note, give the car at least 2-3 days (a week to be safe) of daily driving (must include at least 15 minutes of steady highway driving) after clearing codes, because you will fail emissions for incomplete monitoring tests on e.g. catalyst and EVAP, those take longest to mark complete.

As for driving 2-3 days, I am over on the registration, as it expired end of February. I am careful not to drive too much, but I know I need some miles (is 50 good?) after the code gets cleared.
I already failed the emissions once because of this (and other codes that went away), and the tech at the smog place said he'd tell me if it was ready to take the test without charging me, so that seemed cool of him.
How about this though:
EGR gas temp sensor on'94 Camry, which suggests using an actual resistor in place of the sensor. Is that a good idea? If so, will it be seen and/or detected by the smog tester?
(Side note: I am in N CA, and the car has 220,000 miles. Don't know if anyone needs to know that, but I saw it in another post, so I thought to add it here.)
as mine was, replaced and all seems good thus far...I am holding my breath....good luck, vvs was something like 45 bucks at o'reilly with lifetime warranty.
