Multiple Misfire Cause?
I turned on my car a few days ago, there was a hard start. The car would increase rpm then drop and eventually shut off.
I used the obdII and picked up codes for Misfire in different cylinders and multiple misfire.
Initially, since the weather here in NY has been freezing, I thought maybe water in fuel so I added Water Removal.
That did not work, and changed the spark plugs. I still get the same codes. Any ideas or solutions?
