Hey guys im new here, i have a 2012 eco-screw and love it, but it idles rough ... Pisses me iff, its been. Idling between 990-1000 rpms lately it used to idle at around 5 or 6... Please help... I replaced plugs twice all crafully gapped to .030, i always run 93 octane, livernois 91 octane tune, aem drop in airfilter, i have a nice oil separator on my pcv valve, so ya... Why is it idling soo rough?!?!

Lms tune may be setting the idle speed....

Ok so I'm wondering whats best for replacement plugs on a 2011 ecoboost with cold air intake and high flow exhaust no programmer yet. Thanks and also my truck seems to have a ton of lag any suggestions.

just installed these in my 2011, i still get a shutter 50-60 mile range while MPT tuned... while stock, without tune, no shutter. Any idea?

I get that with the MPT tunes, but not SSI or 5 Star.

How old is your MPT tune?
There was a fairly recent update.

We had a truck at the dealer this week.. All plugs showed signs of carbon tracking...this truck had 80k miles... And a timing chain that was stretched so badly it was settng vct codes....timing chain was replaced but a miss was present under loaded conditions... We found tracking on all plugs

How long should I drive my truck after I set the new gap .028 before I can get on it.

I have currently placed an order for a XLT model with the Luxury Series Package. I still have the option to change my build. Is there any options anyone has but did not care for or do not have and wish they had it? Also, are there any issues that I can expect upon pickup?

Just long enough to get everything warmed up....about 10 minutes depending on the weather. ;-)

Drove for about 25 minuets and it hesitated. I gauged twice to be safe that I had all the gaps at .028.

Are you tuned?

Do you have an OBD adapter to monitor what's happening as you drive?

Yep
Sct can tune, but my hand held got stolen out of truck during Christmas so I haven't been able to monitor anything.

Yeah tell me about it. I know you have to drive it for a certain amount of miles to let it calibrate

You can do a battery pull and see if that cleans the tables up.

Talked to a friend from ford he said change the gap to .032-.035. Only time it's recommend to go lower is on custom tunes

I also got that famous shutter ppl talk about, went threw everything found a hairline crack down one of the spark plugs.

I got an update in November with MUCH better shifting, probably thanks to you. I still have a rapid flutter under load that I don't get with other tunes.

Get the newest, flutter is gone.
