Thank you for the quick feedback.
For the running too rich issues why would you remove the K&N Intake (just curious)? Is this not a good upgrade? I'll try and clean the MAF to see if it helps or maybe the MAF needs to be replaced?
You mention that the normal suspect for those warnings is a Speed sensor. How many are there and how can I test them? Another thing I forgot to mention is the warnings do go off sometimes when I'm in park at idle.
I looked for TSBs for this issue and came across these two:
2012 PIT-5120-A GMC/CHEVROLET/CADILLAC: INSTRUMENT PANEL MESSAGES REGARDING STABILITRAK MESSAGE, TRACTION CONTROL MESSAGE, SERVICE BRAKE SYSTEM MESSAGE, IS OFF AND GAUGES, IN VARIOUS MODULES LOW SPEED SETTINGS, ARE INOPERATIVE. MODELS 2007-13 ALL ESCALA ( NHTSA ITEM NUMBER - 10047479 )
2008 PIT-4665A GENERAL MOTORS: DURING NORMAL DIAGNOSTICS AND/OR REPAIR VERIFICATION THE ABS LIGHT, TRACTION CONTROL AND/OR STABILITRAK INDICATORS MAY BE ON WITH NO DTC'S DISPLAYED BY THE EBCM. ( NHTSA ITEM NUMBER - 10028264 )
My vehicle isn't under warranty - what can I do with these bulletins?
Appreciate your help and any ides!
