Garage said EML can come on and off because theres an issue thats not quite enough to bring up a code. not sure how true that is,

I have a Bluefin remap on the car, so if this PCV valve hasnt made any difference I will put it back to standard, and see how that goes,

Do you know how I would find a local Pro like MSD local ish ? I have been in touch witha few remap places that have said they can remap my car to make it run with all my modifications, but not sure I want to go ahead if it sounds like I have a possible faulty ECU
