For the tech gurus out there...Any feedback would be greatly appreciated!!!! I'm stumped.
1) Friday Night - Installed Steeda cold air kit with plastic inlet tube. Re-tuned with SCT with 93 octane setting and Steeda kit programming. Test Drove...awesome.
2) Saturday - Drove 4 hours and seemed fine.
3) Sunday - Stayed parked all day.
4) Monday - Drove home 3 hours - halfway put in a can of Seafoam Motor Treatment -FROM THAT POINT ON IN HESITATES BIG TIME IN LOWER RPM RANGE. But...doesn't do it every time.
Note: Car has 81,000 miles - synthetic since 2k. Only other mods - underdrive pulleys and Steeda throttle body spacer.
Before I installed my Steeda, I used some sandpaper on the shiny black elbow so that the rubber connectors would stick better. This included the vacuum hose fitting. Check to be sure that it did not come loose from driving.
So...is what I'm describing a classic symptom of air getting into a connection somewhere between the throttle body and air filter?
With change of the CAI, it is a strong possibility. Anytime you make a mod or work on something and then a problem shows up, always go back and look at the last thing worked on first.
Makes sense angcobra...I just can't figure out what changed between Saturday and Monday even after a detailed inspection of the CAI...just a bummer after spending almost $700 and pulling off a no tune CAI that was working fine...

Thoughts?
Thanks, Kevin
+1 that is my first thought also....and get rid of the TB spacer...it does nothing is a freaking paper wieght!!!
Hammeron and Howarmat and ALL- Drove about 300 miles for work today...ran great on the interstate...3rd gear punches at 65, etc. Now it runs like crap in the city tonight- from 1800 rpm on up...Punch it in any gear and it feels like the brakes got slammed on...I've heard of the fuel pump tsb...would this be much worse now with this mod? Any chance the issue is the Steeda tune? I've checked all connections and there is no way any air is leaking. Is there ANY chance this is symptamatic of spark plugs?
This is really, really aggravating me. The car is almost not driveable except at low rpm and very steady acceleration. I was expecting a complete Steeda CAI w/ their tune to be awesome but so far it has been a nightmare and a lot of work trying to figure out why I now have less power than stock. I know their products are good but it doesn't make me feel any better after dropping the cash. Thanks for the Input, Kevin
hammeron - You can tell I'm too emotionally involved at this point because that is a pretty good idea and I didn't even remotely think of doing that. I'm also in communication with one of the guys at STEEDA for ideas as I bought directly from them. Thanks, Kevin 06 Hyundai Mustang GT
For those tracking and contributing to this thread, the verdict appears to be fuel pump (will know 100% when replaced). CAI and TUNE make the car run like a bat out of hell in the morning when first driving begins...after some steady speed high way cruising is when the problems begin.

Well your problem could be the fuel pump, but it's not related to the TSB. The hesitation problem with the fuel pump only happens after driving for a few miles at highway speeds and then slowing down and trying to accelerate quickly. It's not going to happen just driving around town.

Seafoam really cleans things up including spark plugs It may have cleaned them up good enough that it's time to replace them. My work truck recently had a slight miss at 1800-2000 rpms and once I past that it was smooth as can be....go figure, did a tune up now she runs like a champ. Also I would return her back to stock to see how she runs afterwards becuase plugs for these car's are 15 bucks a piece and that would be an exspensive guess
