Limp Mode

Yesterday my car went into limp mode, i have no idea why, and im trying get a general idea on it before going to the dealership. My car is all stock minus axle backs. Is it possible that bad gas could cause the issue?

Try pulling fuse plug 47 for 15-20 mins put it back in and then start the car see if that works for you. i have to pull this every few weeks or my car drives like a mini van

Unplug fuse 47 under the hood fuse box. Leave it unplugged for about 10 mins. This will reset the driving habits it has learned and your car will relearn how to properly run. Might work! Worth a try, good luck.

You should try to describe what you mean by Limp Mode. There is a Limp mode that refers to a safety system designed to protect the engine from being damaged during extremely hot temperatures.
Or is it just a little less aggressive than what it has been?
What does it do when you "gun it" in this so-called Limp Mode?

The Wrench icon lights up on my dash, which according to my owners manual is limp mode. I have not tried to get on it when the dash light comes on out of the fear of causing more damage.

And i thought it may have come on due to it getting too hot, because yesterday is when it popped up, near the end of a fairly long trip (approx 400 miles) but it happened again today about a mile away from home when i left for work.

My car was recently doing this. All I had to do was turn it off and back on it would then drive normal. I put it in the shop and they said the throttle body was going bad. I got the BBK throttle body and have had no further issues.

Excuse me for asking, but did you check your coolant level.

I did, it looks just fine. So I pulled fuse 47 and did the entire idle relearn procedure, along with got a full tank of gas from a different gas station. It didnt go into limp mode almost the entire day. However, after a hard stop (somebody cut me off so i had to slam on the breaks) it came back on when accelerating, it lurched from a stop and squealed the tires even though i barely touched the gas. And then it was like it almost downshifted (automatic trans) and the RPMs jumped to 5-6k. Could a throttle body be the cause of this like andrev6 mentioned?

TB is a fairly common issue and my internet guess too.

Before I did any fuse pulling or other attempts to mask the problem, I would check for codes. There could be pending codes in there that could clue you in.

Is your Air filter clean and the assembly tightly attached to the throttle body?

Beyond that I had a similar problem caused by the Throttle Position Sensor.

I can't say anything because I wish I had bought the Manual in 08. The Autos have been far more reliable in the 11-14 years.

But I can't disagree with strange mud, it's a completely different experience.

Idk, I'm starting to read more and more auto issues....
One thing i can say about our manuals is they suck in the cold until they finally warm up with or without ford's tsb fluid swap.
Could be worse though, my manual could have been built in China lol!

Oh wait......

I had this same problem with my auto a week after buying the car. I doubt anything is wrong with the transmission...my issues was a plug became slightly loose causing the car to go into limp mode. If I shut the car off for a bit it would be fine until I hit a bump or braked hard. They read the code, lifted the car and pushed the connector all the way on, lowered the car and handed me the keys. Haven't had an issue since. My dealership has a ton of real good mechanics, I could see other places reading the codes and just throwing in a new transmission on fords dime. Problem is, with those types of mechanics I then would be worried about the install. lol

For reference the code gave the indication of a transmission fault, but the mechanic had seen it before and new to check the plug first.

The thing that threw me off the most was the fact that there werent any codes. It just went into limp mode, and the transmission completely blew when he took it out for a drive to see what it was doing. So unfortunately it wasnt the plug. The good news is I should have it back by Wednesday. Im sick of my Chevy Sonic rental lol
