So I have had an intermittent engine management light come up on the ff . It ties in with weaping rocker gaskets and a failed pcv. Anyway all fixed now but the light still comes on, sometimes flashing sometimes staying on but by the time I get home it’s gone and it leaves no code in the memory! Wtf how do I troubleshoot this!
