Wrench light again

[robmustang201528]

Car doing it again smh. Having issues with my car throwing wrench lights in 5th gear at high RPM. Hook the SCT to the car and it says throttle body stuck open. Replaced the throttle body still doing the same thing. Is this tune related? Have you herd of a problem like this before? I have longtubes jlt cold air and a tune. Is this tune related? Please help thanks.

LOL it's "heard" not "herd".

Do you happen to have a JMS Pedalmax or any throttle enhancement device on the car?

Typo thanks at Silver GT. No throttle enhancement device at all.

Maybe try telling everyone which tune you are running. Is it an SCT canned tune, dyno tune or email order tune? I feel like someone else has had this issue before. Try doing a search.

check the connector on the throttle body.

It's a dyno tune. Local guy around here. I disconnected the battery for 15 min. Plug it back up, waited another 15 min, made two hard pulls from 40 to 150 no issues. I hope this fixed the problem. Only time will tell I guess

I've only had this happen once. I switched driving modes while at wot. Instantly went into limp mode with wrench light. Switched the car off, restarted and all was well. Scared the hell out of me though. I guess any fluctuation in the throttle that is out of what is commanded will cause this.

Super helpful bro.

Anyways, I believe your model year mustang is subject to a recall that affects the throttle body. I would take a look in the TSB sub section to find out more information.
