Immobizer system i had been out over two hrs in my car came home for min turned care off it dinged saying immobizer system needs service and car would not start back even this morning
Car would randomly shudder and rpms fluctuate while idling. then would just die when attempting to go from idle. eventually asc service required warning came on with service engine light. transmission tunnler was replaced. car ran fine for a few weeks and problem has started again. pulling into gas station, car started to shudder. rpms fluctuated and asc service required came on again.
