With that in mind, if you must adjust it yourself, the engine must be fully warm including the engine oil. With the car idling in park press down on the adjustment tower with the 3mm adjustment tool until it engages screw in the air plate and then press down slightly to deflect the air plate minimally and note if the engine speeds up or slows down. If it slows down, the mixture is too rich and if it speeds up significantly and smooths out the mixture is too lean. Ideally, you will adjust from the lean side towards the rich side to get to the correct mixture. You will get to about as good as you can by ear when the engine idles fairly smoothly (no misfire), a slight push on the air plate screw will cause a slight increase in idle rate (about 50 rpm), your exhaust does not smell of catalyst odor and there is no pop back in the exhaust which would indicate a misfire.

Mileage wasn't that bad 13.5 mpg mostly city. I still don't know which way to turn increases or decreases.
I likely have air leaks. Found a cracked egr rubber. I guess I should try to get it tightened up but I can't get access to some lines mainly the 2 throttle body.
This has been going on since 2007.
My mechanic seems tonthink its running the best it can.
The stink burns my eyes & I'm coughing from a few days under the hood.
I'm frustrated as now I have a incomplete regis. I have a DMV road test 7/9 with likely100 deg temps & I'll have to fall back on the trusty Volvo with No AC.
I'm just trying to get it close & useable until I get ok for the repairs/ adjustment
I was feeeling pops under car from exhaust system.
Luckily right now it seems to be better
'lll try again but I think it slowed down. It was set by a smog place on 09 & passed 2011. so guess it should have been not so off.
I was turning clockwise as suggested to try to get it to slow but it never really slowed.
I just need to know I am understanding correctly.
What screws into the airplate?
Maybe I should turn it back?
Maybe I wasn't depressing hard enough & it wasn't turning?
Maybe I shouldn't be playing with it? I'm not sure how to turn it
I just want to make her better
