Default Dreaded Check Engine Light

Installed LG's last weekend. Routed the rear O2's up in the tunnel as far away from the pipes as I could. Wrapped the plugs in foil tape and fabricated hangers to keep the wires out of the way.
Drove it for 50 miles without a problem. Let it idle for five minutes last evening and the engine light came on and stayed on. No message in the DIC, just the yellow engine-shaped light on the dash.
Sure hope I didn't fry the sensor plugs. Plan to put it up this weekend and check. If they're fried, I'll have Alvin tune out the rear O2's on Monday.
Any other suggestions?
TIA
Bob

your code is for the rear 02's. also I didn't have 1 plug wire on 100% and it had a miss. Your tuner can delete the rear 02's

But if the plugs weren't on tight from the getgo, I would have had a miss and engine light right away. Light didn't come on until 3 days after the install with no engine miss.

If your luck is like most of ours, you have the P0420 & P0430 codes, only permanent fix is a tuner. Read the codes to see what your exact problem is. C6 CEL's require a scanner thats CAN enabled.

ok
then I'd bet a dollar that its your rear o2 codes. It took mine a while for the CEL. your tuner will delete them. no worries.

if you don't have a code reader you local auto parts store can pull the codes for you. it is better to have it pull just in case it is something else. tuner can tune this out if you are getting a tune any ways, just make sure you don't get charge again if you add more mods later. if you are not going to do a tune therre are kits out there to get rid of CEL for folks with headers / no cat even. just pm me.
