Hi all
​​​​​​New to this but need some help
When I'm driving around 60-70 mph the car starts to miss fire and ems light flashes then goes off then drives ok but it starting to do it every day now I have no codes coming up, any ideas pls I'm a carer and really need help
How do I check the coil packs with meter and which pins do I use to check and what ohms should they read, or could it be spark plugs
Or any other support would be much appreciated
