- 2014 Ford Explorer Sport
Hi All,
I’m having some serious troubleshooting issues. I have 2014 Explorer Sport with 107,000 mi. May 2021 at the 100,000 service a leaking water pump was discovered. The water pump was replaced along with the valve cover gasket, and spark plugs by a local service shop, not dealer.
Since then, the car has had multiple P0420 codes, but they come on and off intermittently.
2 weeks ago I added Techron Fuel Cleaner, and for that tank of fuel, the car ran better. On the next tank, the car began misfiring on cylinder 1, 6 and threw engine codes P219A, P0301, P0420, P0011, P0018.
I had to pull into a local shop which identified ignition coils, and shortly there after realized that the ignition chambers had flooded with oil, due to spark plus tube seals not being changed during the initial water pump service.
Now the spark plug tube seals, spark plugs, and ignition coils (Carquest Premium coils, Motorcraft wasn’t available).
The issue is the car is idling poorly and even feels hesitant at speed when in gear around 2,000 Rpms.
The shop cleaned out residual oil in the engine system yesterday with seafoam, but the issue is only slightly better, causing the occasional red light stall, or reverse engine stall.
Are there any obvious missed troubleshooting steps and solutions to what may be the root cause of the ignition issues?
Any help will be greatly appreciated! Many thanks in advance!
