Hi all,
I have a Roush supercharged 17 GT. I had the OPG etc replaced with billet parts. I have 8800 miles. Temp today is 30 degrees and I HAD to take it out today. Wife is using my DD while her car is in the shop.

I do not believe this is SC related, but don't really know what happened either...

I was accelerating on to interstate, gently as I have summer tires on (again, I didn't want to take it out), fifth gear rolling on from 50-ish to 70, I will also mention the car was warmed up before I left the drive way and I had already driven about 10 mins... There was a stutter and here is what I experienced:

-dash message "Drive mode not selected" -- I think this is what it said it popped up and disappeared pretty fast
-orange wrench icon
-see owner manual dash message
-oil pressure went from 80 to 60
-AFR went from 13/14 up to high teens/20
-head cyl temp was at 207
-a couple miles from home, babied here, nothing is leaking from the car. It lives a nicely cared for life in a nice garage :)

I am hoping that the stutter, AFR, etc are symptom of limp mode, which is what appears to have happened. Just need to figure out why now.

I have an ODB2 scanner on the way, but in the mean time I am looking for some glimmer of hope that this is not a critical issue.

Thanks!

How long had it been sitting? Maybe bad gas?

about 2.5 months at this point. I am ashamed to say that this year I did forget to add sta-bil to the tank.

I wonder if it wasn't some sort of electrical/grounding fault? It sounds like multiple systems got tweaked. Hopefully it isn't anything major. It really doesn't seem like an actual engine problem from what you have described.

Wrench icon is most often related to throttle body. Many threads on this warning icon.
Second this. I had something similar happen with my Edelbrock kit because of a fault extension harness. I'd check to make sure that the connection is solid at the TB.

had something like this happen on my whippled gt... was hesitant, sluggish, not responding to throttle. Threw the wrench light. I pulled over, turned it off and once restarting it it worked just fine. hasn't happened since

The same thing just happened to me on the highway. Was driving went to pass someone so I gave 1/2 throttle, went into boost (procharged); and got the wrench/said no driver mode selected. Babied it home for the next mile or two with low 12afr/low vacuum thought maybe belt had slipped. Turned it off when I got home, checked engine bay no smells, leaks or anything I could see was wrong. Turned it back on put it back into sports and gave it about 4k rmp rev and it was good. Here's to hoping it never happens again!

Mine went into limp mode often with the Roush tunes (1&2). Never anything more than shutting it off and on. Generally happened during normal driving, once during “spirited driving”. Hasn’t happened since the VMP tune. Just sayin...

My whipple car throws the wrench light sometimes if I park for a short period and then start it back up. I can immediately turn it off and back on again and the light clears. I think it does some kind of throttle body calibration right at start up.

Thanks guys. At the very least I don't feel suicidal anymore LOL

I got my ODB2 scanner today. I walked solemnly to the garage to plug it in and see what kind of damage was done. Pushed the start button to turn on accessories and hit scan. Nothing showed up... so I said to myself “self, I really don’t want to start the car but apparently I must have to start it to see the error...”. Held my breath, foot on break hit the button and awaited a metal on a metal screeching banshee noise. It never came and neither did the wrench.

So I let the car warm up and went up the interstate, no wrench. I didn’t think I could be that lucky so I jumped on it pretty good and no wrench. Woot!!!! Go me!

I did see an error P061B Internal Control Module Torque Calculation Performance

Not really sure what do about this, or if maybe it’s there due to the SC?

Thanks for all the feed back. I love this site!

"I did see an error P061B Internal Control Module Torque Calculation Performance"

This generally a tune issue and not hard part issue if there are no obvious wiring issues as previously mentioned. Many people have fought this issue to have it resolved later by changes in tuning, the torque/load calcs may be slightly off in certain airlflow areas and there is not enough allwoable wheel torque error in the tune to allow for the miscalculation so you get the PO61B error and wrench light. However it's dangerous to just up the wheel torque allowable error in the tune because this is one of the checks and balances the pcm uses to administer torque to the driveline. When you step on the throttle you are actually telling the pcm how much torque you are expecting the coyote to put out.

Consult your tune provider after checking your connections.
