ok i know what all of the codes mean, so no need to tell me. but this is the deal, i was on the JRB and my CEL came on. i jumped it and it was either 10 or 1, then i disconnected my ECU. when i plugged my ECU back in 10/1 was still on along with 6. i stopped by Tuners Edge and chris told me they could be ground related, so i swapped to a couple different ecus there but they wouldnt flash the code. so i swapped back to my ecu and the codes were gone, but i had code 21. WTF mate! someone explain what could be going on. i checked my grounds, all of them in which i could see. anything i can do before taking it to the shop?
