Cant make sense of codes

[Brett]

Well posted on trying a cheapo code reader, oddly enough, just like the thousand(s) dollar unit at a shop, it said ECU wouldnt respond, so im thinking im not using the code reader right, nor is the shop! Anyways, i did the paperclip thing and as said before im horrible at reading the blinks. Heres what i got, please try to make sense of them as best you can, I know i mis counted on atleast a couple. This is what i got before i started it with key on ON positon:

252
959
155
7(or 8)54
7
1
412
538
521

Once the car was started:

412
538
521

I know the last two after the start are because i didnt do the wheel test or the "goose test" whatever that is. Any help is appreciated, thanks guys!

I think it'd be in your best interest to go back a double check the codes. Not verifying them would be the same as playing the guessing game.

When you finally get an accurate reading of the codes, here is a translation of what they mean, roughly:

It's not going to tell you EXACTLY what is wrong, but it will point you in the right direction. You have to diagnose the rest yourself.
