I've searched, so I guess this isn't terribly common:
(also placed this thread here, as I don't believe its a warranty/service type issue unless the new factory ford wiring is at fault)

My car just had an issue where it went into limp mode because it saw 0 on the TPS voltage, voltage had dropped on a wot run and zeroed out. After restarting the car, everything was fine, drove home without issue.

I've cleaned and checked the plug, the operation of the TPS, and am adding a second ground strap (since the TB uses a chassis ground) to see if that helps. Otherwise monday the accufab TB gets shipped to accufab for repair if I can find a stocker to test against and verify the problem exists in the throttlebody (it uses Ford electronics)

Anyone run into anything like this? It is just my luck, lol.

Looks like it was. One blast up to redline to test was ok. Will have to hook up datalogger and see if I'm resolved

Mine did that to me the other day, it hasn't happened since, but I haven't done anything to it, so I dunno. What's that picture of?

Well I still have this issue after all this time. Got a replacement throttle body from accufab and all grounds are good.

I'm going to have to start from scratch on troubleshooting this unless anyone has some ideas.

no codes thrown on mine, AED is aware but believes it to be the throttle body though I'll talk with them today.


here's video of the super-fail drag racing pass:
Drag race fail - YouTube

Its a bad launch, then followed by lots of wheel spin, more wheelspin, a shift to second (more wheelspin), and by the time I get into third, shutdown. during this "wrench" limpmode, no throttle actuation is possible until key off and back on (as at the end of the video)

How has this changed from your other issue with the cracked spark plug?
