I'll get my battery tested today, looking at getting an interstate battery.

Any feedback on Interstate?

S197GT07

Have you tried replacing (At least) one of the front O2's?

They're like $20, and it would rule out at least that being an issue.

I have always had luck with Die Hard batteries (have one in my Mustang now), but I'm sure that Interstate batteries are fine...

Attached battery again and there were no codes being thrown out, except my tire had low pressure. That went away quickly.

This morning I went ahead and cleaned part of the throttle body, when I removed GT500 air tube the TB showed very little residue. Butterflys were clean. Just wiped it down a bit.
Seems alot of guys add an oil catcher, but it seems thats not an issue with my set up. Thats about 13,000 miles since SC install.

Cleaned the MAF, which was very simple to do.

Took it for a spin to get paint for the chin spoiler and everything seems to be fine. No stuttering at low speeds and no codes being thrown out.

Will see what happens on a longer commute tomorrow.

Looks like it was part Battery and mostly poor gas.

Only major brand Gas from now on!

The build up of oil from the PCV system forms on the intake manifold side of the throttle body. You will need to remove the the throttle body to clean it properly.

And you definitely need a catch can with FI! The last thing you want is a coating of oil on the fins of your inter-cooler!

Good to know about throttle body, will take it off soon to check it out.

Well it was not bad gas, and not the battery.
Took the Mustang to PCM and Eric quickly found a tube that had become loose from the manifold. I must had knocked it loose when charging the battery.
Wish I had found it sooner, had to drive it like grandma.

Had a Camero and then a Challenger both want to test out my stang, but all I could do was wave
