I cant paper clip it or at least I didnt figure out how.I just go to advance auto and they scan it for free there.Autobones wont do it anymore.
Btw I dont recognize those codes...the OBD2 codes Ive seen are usually P01080 or something...P0300,P0301,etc etc for example.At least on a scanner...lemme check something and get back.

Thanks guys. I found the codes in my service manual. It looks like I got these codes from trouble shooting my hard start condition. The codes are related to the MAF, Coolent Temp Sensor, & Injectors.
This has lead me to start my opti replacement. My engine is getting to much fuel & not enough spark.

So you get codes for the MAF, CTS, and injectors and instead of troubleshooting them you replace the Opti which has it's own set of codes?!

Here is the complete story
I've been chasing a hard start but it really wasn't that bad. I took it up to the goodyear shop to get the radiator flushed & filled. When I got it back the mechanic said that the coolant temp sensor & pigtail was shorting. He said it was a common problem on a 350.
Then when they handed over the keys I couldn't get the car started. We had to play with the MAF & injectors to get it going. The mechanic that help me get it going told me that the opti was going out.
So I'm suspicious if they got coolant on the opti & finished it off.
Now I got the car home & ordered a bunch of parts & am going to replace the opti & some odd ball components up front. It will probably take me 2 weekends & a couple of trips to the fridge.

They also have some OBD2 codes implemented, but you can't get those with the paperclip.
