so about a year ago my car started lighting up the abs/trac lights. i figured it was no big deal but took it to midas where one of my friends works and he threw the computer at it. he said its saying the left front wheel is putting out erratic signals and its causing the abs and trac to turn off.
on a side note, if its below about 65 degrees they wont kick on (lights) but my trac loves to kick on and limit my power when im trying to, oh i dunno MERGE ONTO A FREEWAY and the abs absolutely loves to scare the **** out of me when im pulling up to stopsign and make me roll halfway through them.
but i replaced that bearing/speed sensor in march, thinking that would fix it but it didnt. i traced the wires as far as i could see/feel them and they looked fine... do you guys have any ideas? ive got my multimeter now if you know any voltages/resistance im supposed to check for.
id just really like to get this fixed before winter. because, to stay on my moms insurance ive gotta keep it registered to her in lake county. one of only 2 counties in indiana which require my car go through a saftey/emissions test.(by 12/9/11) and if my car came stock with a saftey feature it wont pass unless its working.....
thanks alot for any/all suggestions.

Here is a test. https://www.gmforum.com/trouble-shooting-test-procedures-141/wss-wheel-spin-sensor-test-296556/ But seeing you have replaced that sensor and the problem is still there, I would suspect the wires. I've seen odd ABS signals come from water in the plugs.
