stumble at idle

[Back from thr darkside]

It started yesterday truck runs fine but when I put it in park there is a slight stumble at idle.It's not constant I would say every 30 seconds or so.Any ideas or anyone ever have this happen to them.Thanks in advance for any input.

Well I detuned it down to the performance tune from the extreme and it stopped.I'm wondering if I need to put a cai on I had to reset the button on the air box every time I drove with the extreme tune.

Derek which tune and do you have a cai?

[derek4real11]

no cai and extreme tune. i do have some new info. i took my truck to the dealership cause i got a letter saying the computer needed to be upgraded. my sct programmer also had an upgrade for it on their website so i did that too. after i got it back from the dealership and put in my new upgraded tune(extreme again ) the stumble or hiccup as i call it is gone now

It may not be your motor mine did that and about 3 months later my torque converter went out

Makes me wonder I'm pretty sure I have fords latest flash since its been in the shop 3 times in the last month and I updated the firmware on my tuner unless sct has a new update since a month ago.Anyone know if there is a new update from SCT?
