Well after doing a ton of research on this forum I cant find anyone with the same Issues/codes I am getting. I do see alot of posts related to Rough Idle, skid light, shaking, etc. But all those posts have a CEL of p0016-p0019.

Car currently has around 43,000 miles, Only engine related mods are Blitz intake, ARK exhaust, and catch can. Intake and catchcan have been on for almost 2 years, exhaust about 5 months.

Car started to idle rough a few days ago, RPMSs dropped to below 400 and would stall I did not rev it. Also when i came to a stop the DRL's would turn off and on. CEL came on and at time the skid light would light up and stay on. Also cant use the cruise control, "assumed that was just a precaution of the CEL"

Took it to the dealer today and the codes they pulled are

P0172 Bank 1 rich code
P1170 Fuel performance port injector
P1178 Fuel performance direct injector cooler
P1604 Start ability malfunction

Tomorrow I will try reverting intake setup back to stock and do a battery disconnect / clear codes with torque.

Anyone have any opinions on the the problem?
