I hope you mean to yourself, because TRUST me a bad gift such as stretchy pants is unwise. On the other hand the doctor says there shouldn't be any scarring....[emoji38]

Problem solved!
 
It turns out after two treatments (one really) of injector cleaner I have solved the cold start misfire issue. For the past several days, and some were quite cold, the X has started and run smoothly. No misfires and no SES lights. I used a half bottle of Techron in a half tank of fuel, then a full bottle and the ramainder of the first bottle in a 20 gal.+/- fill up. It has not misfired now in several days. Many thanks to Jeff O and upallnight for pointing me towards dirty/sticking/leaking injectors as my problem.

possible maf?
 
I'm having a similar issue with a misfire cylinder 1 with fuel cut.
loss of power, i unplugged my maf and power was restore but still have the check engine light and rough idle.
possible the maf or vac leak.
also with maf unplugged i dont get the misfire code. just a maf code

You should start a new thread on your problem.

Glad you finally fixed the problem and didn't fire the parts canon like so many people do on this forum.

And I'm glad you mentioned the injector cleaner. I never did that and only get rare occasional rough start with cylinder fuel cut off.
