That’s not what I wanted to hear. Lol

The plugs that come with the kit are CYFS092YPT aka ILTR7N8 aka an NGK plus in the 7 heat range aka identical to the NGK6510 with the exception they come pregapped at .035 for boost applications and are actually a better base in that it you want to tighten that up NGK only recommends a max of .008 gap change which puts the 6510s put of range to run .026-.028, though many do....its literally the same plug when you cross the numbers all the way back to the source in Japan......dont ask me how I knowThat’s frustrating , are you running the Motorcraft plugs that came with the kit ? I was having some random misfiring so changed plugs to NGK seemed to take care of it .
You should notice with it hot and heat soaked you will turn it off let it sit for say 15 mins and hit start does it stumble there as well?That’s not what I wanted to hear. Lol
Something harmless to check are the pins going into the TB connector, I had one unseat and it give me the limp mode put me on road...ect.....Never had a warm start issue. It’s when running already that it stumbled at idle. I had three different codes once when it went into limp mode, not the ones you mentioned, which I believe were tied to the 103mm TB. Car is driving ok minus some rough spots in the tune. I’ll keep this post updated.
Looked back in my emails is was P2119 code when I had the TB harness issues it seems just glancing thru.....Something harmless to check are the pins going into the TB connector, I had one unseat and it give me the limp mode put me on road...ect.....
P2119 was one of the codes I got when it went into limp mode, too. Re-loading the tune helped fix it.Looked back in my emails is was P2119 code when I had the TB harness issues it seems just glancing thru.....
Good just trying to help I had all the early growing pains on both stages....I found the pin itself wasnt well seated in the connector....P2119 was one of the codes I got when it went into limp mode, too. Re-loading the time helped fix it.
I know you've mentioned that you like the Stage 1.5 idea, which I assume is going from a 3.5" blower pulley to a 3.75". I'm probably going to go this route to make it more survivable on 91. If you did this, what belt size worked with the 3.75" pulley? Thanks.Good just trying to help I had all the early growing pains on both stages....I found the pin itself wasnt well seated in the connector....
On the surge I found a KAM reset AND a crank relearn will really help after about three drive cycles should be a minimum.
Also and other more experienced Ford techs would have to tell you, BUT the FORD IDS, always seems to do a better job of the crank relearn and even resetting trans after a tune.....if your friendly with your dealer takes em 15mins.......
Also I've had this happen more than once if it continues to surge at idle double check that your air filter has come off inside your air box.....
Good luck it's an awesome blower and in stage 2 93, you should eventually be able to get where its driving pretty darn nicely.....
K080860HD fits perfectly and it's a gates HD green belt, cheap from Rock Auto.....I know you've mentioned that you like the Stage 1.5 idea, which I assume is going from a 3.5" blower pulley to a 3.75".
