I've gotten some suggestions to check my TPS, but how would I go about doing that? Is it an inspection check, can I do it on my handheld, or do I need to take it to Ford?

 

Did you make sure your intake is secure?

Ya never know.

 

Yeah did that...I didn't drive it today...worked from home...but since I am tracking down a problem....I'll check anything that it could be that way I either find something else, make sure everything works, or by doing certain things prolong the amount of time before it needs to be checked again...

 

I think it is fixed...for reals this time.

Started acting weird last night, but nothing too bad. Went into limp mode, but came out after a restart.

This morning started the car and decided to run up stairs and grab the tuner just in case to try to read the soft codes from limp mode. Well guess what by the time I came down it was already in limp mode and had thrown a CEL!!! YAY!!! Finally, hard codes to give the dealer.

So I managed to limp the car all the way to the dealership which is a mile from work, so about 25 miles at rush hour. I get there and the car loses ALL throttle in the dealership parking lot. And I mean ALL throttle...press the gas and it continues to idle. So the service advisor helps me push it into the service drive. I tell him the codes that I got from my Predator and leave around 7:45.

At a little before 11, I get a phone call. I think this is really really early. They either need to order parts, or they aren't going to warranty it because of the intake and tune. Nope, I was wrong. "Mr. Gau, your car is done and ready for you to pick up." Whoa, are you serious? Yup, he was.

As I had really started to suspect the cause of the problem, it turns out I was right. They replaced the throttle body and throttle position sensor. So hopefully, I am done with this idle non-sense. Now if I could only figure out the charging system thing too.

But I have to give it up to Five Star Ford in south Scottsdale. They didn't even hassle me about the mods and I had the car back in near record time w/o an appointment. Now that is what I call service. No car wash, but that is okay because I really don't trust some 18 year old kid without even a GED to wash the car anyway.

So now we are going good and still with 3 months and 7,000 miles left on the warranty. Hoping the charging system/dead battery thing gets figured out soon too.

 

wow, score, looks like you've got a rare good ford dealership.

 

I had the same problem with my 06 auto; they changed out the throttle body and it got better but still idled lower than normal
