Code Questions

[vrinner]

Just ran the codes on my race car tonight and was wondering which ones I need to worry about (or all of them?) I'm guessing a 26 is bad but the rest? Any quick suggestions. Also a couple of the codes at the bottom I cant find any info on.

Thanks!

Too much garbage to sift through?

Here's what I'd do.

Clear all codes to start with and start with a clean sheet of paper.Then do the test again.

GAboySVO posted a list of trouble codes recently. I'm too lazy and my Snap-On scanner displays all the info for me. If you have a non-original ECU from a T-Bird, you may get tons of codes that are useless.
