Ok, the dealer wants thousands to "diagnose and fix this"... no way in heck because it's not even guaranteed...
Now it's throwing a U1153 code in addition to P2431 and P2433
the original code I got never showed up again after I reset them the first couple times...
the weird thing is this all started this way... I did a remote start on my car, it was running fine, I got in turned the key to run, When I did that the car instantly died and started itself back up almost like it never died but I know it did for about 1 second... when it came back on that's when the CEL came on... and gave me the initial codes I got... that have been showing up ever since...
