My check engine light came on and I took it to the shop. THey replaced another coil. I think I have replaced 6 of the 8. A day later the CEL comes on again. When I am running around 60mph it will start blinking and the Air Conditioning will stop cooling. The engine runs rough too. Any thoughts? Thanks in advance for any help. Rick

 

Nothing? Could there be a vacuum leak causing this?

 

Need the code again. Vacuum leak will not really cause much drivability problems at road speed.
