Brief history:
- Last year I changed my plugs... slight oil on plug 8 (I believe it's 8... driver side rearest)
- After the oil change, on first start up, I noticed smoke out of the exhaust. Figured it was maybe just some grease or something burning off. This eventually stopped all together.
- Also, a burning smell occurs when I get to about 3000 rpm or so and the car feels like it misses or gets choked up
- No issues when I drive with a light foot
I decided to change the plugs today in hopes to rectify this burning smell and that choked up feeling, since I only noticed these things to happen after last spark plug change. Pulled out the number 8 plug and there was oil on it and it seems like there's a bit more than last time, despite the time of change being much less. It's only on the bottom half with the threads. Went from NGK back to Motorcraft this time around and ensured all were gapped the same and correctly. Using dielectric grease for the boots as well. Not sure if the oil in the plug would cause the "miss".
Thoughts? Looked through some older threads as well but just asking because....
