Feels like a SLIGHT misfire or even shake when first start and run of the day. Once in a while when cruising along you will feel the slightest shudder or miss. Tachometer doesn’t dip at all.

The dealer scanned for codes, misfires and everything else. Said they couldn’t duplicate during their multiple test drives (had it for five days) other than once and it was so slight they considered normal. However, of course they recommended a “tuneup“ which of course is just new spark plugs.

i decided to pull One tonight and had to use a 18 inch breaker bar to get the spark plug out. Makes me wonder if they changed them.

Im hoping I’m paranoid.

Heres the pics of one plug.

If they changed them, this is a new plug with less than 200 miles.

And it was so easy I can’t believe I paid them to do it!

but she was there for an axle seal under warranty. Which expires 10/31.

Thanks. Makes me feel better.
And I should add that the grease on the tip of the plug looked new.

Whew.

im thinking I’m expecting too much.
This truck is smooth as butter other than the first few miles.
And it isn’t bad. Most can’t feel anything.

Felt it stutter, more like a kick, once tonight.

Dealer put in plugs. They are labeled ford cyfs12f1

Warranty is out soon so I’m being ultra paranoid
