Car running rich and engine cuts off while idling. Please help.
 

Hello everyone. I am currently having some issues with my car that have me running in circle, trying to figure out where the problem is. The problem started with code p0300 thrown occasionally. Just recently, I changed my coolant for the radiator and the intercooler. I also cleaned my maf sensors with maf sensor cleaner.

Check the MAFs: make sure the electrical connections don't have any broken/bent pins and fit snugly when plugged in, check for air leaks between MAFs and ducts, verify MAFs weren't damaged during cleaning, etc.
