Got a CEL, possible culprits.
So I have been driving the car the whole weekend without it lighting up, and then today I get one after 45 miles of driving.
I have everything connected that should be connected so I don't know why im getting a code.
Is it possible it threw a code because im still running a bit rich in boost? or is it not smart enough for that?
Any way to troubleshoot it without reading the codes off, or should I just go to the autozone and have them pull em for me?

Some research proves that it could be the culprit. Because there are obd2 codes relating to a/f ratio being to rich or lean.
http://www.miata.net/garage/obdii.html
P1131 HO2S Bank 1 Sensor 1 Signal Below 0.45v (A/F Ratio Too Lean)
P1132 HO2S Bank 1 Sensor 1 Signal Above 0.45v (A/F Ratio Too Rich)
P1143 HO2S Bank 1 Sensor 3 Signal Below 0.45v (A/F Ratio Too Lean)
P1144 HO2S Bank 1 Sensor 3 Signal Above 0.45v (A/F Ratio Too Rich)
P1151 HO2S Bank 2 Sensor 1 Signal Below 0.45v (A/F Ratio Too Lean)
P1152 HO2S Bank 2 Sensor 1 Signal Above 0.45v (A/F Ratio Too Rich)
How do I know which sensors these are? 3 sensors?

P0170 Fuel Trim Malfunction (Bank 1)
Its not even in the list at the above link.
Edit:
I was reading through a bunch of forums and it seems to be Air/Fuel related, either MAF, or O2.
Was this what you were seeing braineack?
I guess this could be caused by the MAF getting one reading, and then the exhaust having completely un related readings. I would imagine the computer some how compares ingested air to what comes out.

Spend the $40 for a Code-Scanner... OBDII isn't going anywhere for awhile. I hate relying on AutoPepNapaBoys for anything like that.
I can almost guarantee you it's a rich/lean code... but you can't guess at **** like that. It might be something dumb like an EGR code cause you didn't tighten your gas-cap down fully. Buy the scanner, it won't be the last time you need one.

I didnt go to napa to get it read, a friend of mine has a MAC obd reader and he stopped by last night.

How many Sam's does it take to find a $40 code scanner?
