So recently bought the 02 Eddie Bauer, 4.6 red and began noticing a miss and roughness under load. No check engine light..... For hundreds of miles...
Finally under a good load uphill, I did not let off the pedal and finally a check engine light on with code P0306.
Got home and checked out the coil pack on #6 cylinder... Seemed a bit of discolor on the boot.. Perhaps from southwest red rust or from the powering steering pump near it. I hit the hole with air to get any particles out.
I did not pull the plug as I am still uncertain about process, Tsb, etc on these aluminum head engines.... I hope to do the plug change soon though.
If anyone can point me to or outline the specs, tsb, and notes for spark plug replacement, please do as it would save me time.
I swapped the #1 coil with the #6 to see if another CEL would stay on 6 or follow the coil to 1. Well I never got another light despite the miss and jerk still occurring.
Finally went to junk yard and they sold me a complete 8 pack from a 04 town car 4.6 for 25 bucks. Got home, ohm tested a few, around 1.9 to 2.4 on primary Choose the cleaner one closest to 2.0 and 5000 to 5700 on spring to connector.
Swapped out the suspected coil.... Drove it almost 100 miles today and no miss under load now.
I never like to replace parts as a test when it cost money, but this time I figured it would be worth the cost as I felt strongly it was the coil.
The old coil seems with specs when ohm tested....
After 70 miles I disconnected the battery to reset the ecm strategy. Last 30 seemed decent and it appears to be relearning now. Kinda sucks as I recently paid for an oil change, and now from the miss I do smell fuel in the oil.
I still have a fluctuating idle and the annoying air intake whining noise and I well have them in their own treads.
