Hello, my name is ***** ***** I'm here to help get your problem solved. Is the check engine light on or does it come on when trying to drive vehicle? Thanks.

It flickers but doesn't stay on

It sounds like you may have a failed coil. Use a spark tester to see if each coil jumps a 25kv gap, replace any coil that doesn't. Let me know how it goes, thanks.
