Car idles rough when on E and check engine light goes on, check engine light goes off when filled to half a tank. I recently had to repair the heater switch. Went to autozone and checked for codes 1. P0113, P0421, P0107 this happened ALL AT ONCE. Please help
check says it could be catalyst converter, Heated oxygen sensor in the rear and Map Sensor, Open or short circuit conditions
