    Digital Tuning 2005 Mustang Gt Idle Problem

    Stumbled into a local guy who has an extensive tuning program - he was able to "dial it in" for exactly what I wanted. He did see the thorottle plates closing too slowly and MAF was off a hair probably due to K&N even though it is factory replacement. He also was able to change the RPM drop...

    Digital Tuning 2005 Mustang Gt Idle Problem

    Yes - all started with tb clean. Talked to ford mech - been on them over 30 years - says that is the way it works. He said should be no abnormal clutch wear from rpm staying high between shifts not to worry about it. I showed him my fix for TPS screw - he said that is what he would do with it...

    Digital Tuning 2005 Mustang Gt Idle Problem

    2006, no hesitation, K&N filter not kit - lives in stock airbox.

    Digital Tuning 2005 Mustang Gt Idle Problem

    Have to revise info - just drove and the rpm kick up can happen at any rpm, but more prevalent today in the 2000-3000 band. Early in the drive today the rpm dropped well from 3500-4000 during shifts. but as car got warmer the rpm kick up thing even got up in that range sometimes

    Digital Tuning 2005 Mustang Gt Idle Problem

    Based on car tach - no scan tool, no headers, all stock except brand new K&N for stock breather. Oil change yes, but well before these symptoms. Eng brake with my foot completely off accel - as I said noise and performance different than before clean - seems like throttle does not close all they...

    Digital Tuning 2005 Mustang Gt Idle Problem

    No rough running, no codes, and sounds very similar to your ride. Other things I did were disconnect battery for 30 min to clear initial check eng light, sucked a can of Seafoam thru brake boost vacuum line, and replaced stock air filter with a K&N that fits in stock hole. I still would expect a...

    Digital Tuning 2005 Mustang Gt Idle Problem

    I have a 5 speed as well and I don't leave any hp unused! The idle response now sounds much like yours, but before I cleaned it snapped right back to around 650 without the 1000 hang (engine braking was much better then). Does your rpm hang up high during shifts if rpm > 3000 ish? If I do drive...

    Digital Tuning 2005 Mustang Gt Idle Problem

    Ok thanks - give it a try. I have changed throttle body parts before on other vehicles with no problem at all! Once I get past the broken screw I would still like to see a quicker rpm drop during shifts and a slightly lower idle. I did see mention of adaptive learning (idle and auto trans shift)...

    Digital Tuning 2005 Mustang Gt Idle Problem

    I did not have codes - but could not leave well enough alone. Idle getting a little better but still a little high. I cleaned MAF, and thought I would pull TPS/actuator to see if any play on shaft or debris etc.....stinking TPS bolt sheared right off. Only the bottom one good now. I doubt an...

    Digital Tuning 2005 Mustang Gt Idle Problem

    I hope I didn't screw the pooch but took off throttle body and cleaned it, once again manually pushing open to get everything. I disconnected battery while I was cleaning, reinstalled and idle is fine. Doesn't fall too quickly when I shift, but high idle seems to be cured. Drove a few manuals...

    Digital Tuning 2005 Mustang Gt Idle Problem

    I evidently have done the same thing on my '06. I cleaned twice - first time forced open with key off, got check engine lights that cleared themselves. Second time I had someone sit with key on and held accel to floor. I get much better throttle response/control at low RPM, but returning to idle...
