Hello

[Bklynite]

Hello SHO world,
I own and drove my 2004 P71 since 2010, I installed a Tork Teck roots S/C 8lbs, Stainless Works headers ditched the cats, jmoded had 3.73 installed but i should have gone with 4.10's and some other goodies, prior to that 04 SCT Focus, i got tired of it because of all this traffic in South Miami, prior to that 89 Mustang Gt 5spd.
Ive always owned a Ford, hardly ever have i had any problems with any of them. I was craving a F250 SD till I stumbled into my
2011 SHO I purchased 3 months ago, every one i come across gives me nothing but compliments about it, I really enjoy how quiet it is compared to my CV & Im always open to experiment on my cars, which is why ill start a new post asap about weeping hole.
Looking foward to any suggestions and info anyone can provide.
Have a wonderful, productive year.

it currently has 124k miles, the only thing I've done as of yet is, installing Autolite Iridium plugs @ .30 gap
New Motorcraft coils, changed tranny oil and motor oil. added some gear oil to the PTU.
sputtering started about 3 weeks ago.

If you would like to start a seperate thread on the sputtering feel free.
Did the sputtering start after changing the plugs?
Did you notice any oil inside the spark plug wells?
I would also grab the oil dipstick and remove the TB hose and check to see how much oil,water has accumulated inside the CAC (intercooler).  Z
I would also change the PCV valve for good measure especially if original,some preventative maintenance might be warranted.

Welcome to the community, Bklynite!

Sputtering could be from 2 well-known reasons:  1] A misbehaving fuel injector, and/or 2] chafing knock sensor wiring.  It is also good to check the PCV/EVAP components mentioned, as well as turbo piping/CAC for oil/water/fuel crud accumulation.

So the first thing to do really is to get set up with an OBD II adapter and Torque Pro / Forscan Lite software.  This will help you monitor the car as you drive, and very likely pinpoint the culprit.  Both allow you to log the data, which is very helpful for offline analysis.  You can also pull up trouble codes with the software, as trouble codes do not necessarily set a check engine light.
