Closed loop malfunctions, stays in open loop.

Post by 402Car_Kid »

Hello I've been having a problem where my car will switch back into open loop and trims 0 out until I restart the car. Stock 08 k24a2 swapped del sol. The problem has been gradually getting worse and happening way more often. Mostly happens at idle like when I'm sitting at long red lights. At first it only happened when it was the first start of the day, I would let it idle to warm up a bit and 3 or 4 mins after being in closed loop it will switch to open and then zero the trims and also it will be 16afr. I've asked everywhere and came up with nothing. Please help!!!!
