Unknown problem w/ Acura TL help please
So im crusin in second gear and all the sudden i get a loss of power. My engine is not responding to the pedal, like i was running out of gas. Next my Engine like turns on and it feels like the computer put on this 10 mPH governor on it forcing me to pull off the road. I turn off the car let it rest and then it worked fine. wheeew. But weeks later it happens again then again more and more frequently in first second and third gears...and when on freeway jerks in gears 4-6. today i start it and puting the pedal to the metal the car would only go 5mph. hour later it moving normal except for jerking on slightest pedal movment.. My mechanic says its the throttle body .... Has anyone here has experienced similar symptoms?
Thanks in advance for your feedback!

Hi and welcome to acurazine! Your post belongs in the 3G TL section so I'll move it for you.
The problem seems to be your APP (Acceleration Pedal Position Switch). When the car doesn't recognize the signal from your accelerator, it goes into LIMP mode so you don't kill yourself by speeding uncontrollably and as well so you don't damage the car. Many other folks have had this problem. Search for APP sensor and you'll see the results.

Maybe APP sensor, although generally once they fail, they fail totally. And should have got a CEL and code.
You are 6MT, correct?

Then it should have thrown a code...
Are you saying your mechanic hooked up a code reader and couldn't find a code?
Or he didn't check for a code?
I'm pretty sure it's the APP sensor. They've been going out at somewhat alarming rates on 04 and 05 TLs. They are easy to replace yourself, but they may be difficult to find right now. They were on backorder... I think cost is about $130.
If you want to be sure before blowing $130, take it to Autozone or etc. and get the code/s read for free...if you can make it that far...

Sure thing. It could still be the TB, but I kind of doubt. Need to know what your mechanic found for the codes...

I'm going to guess the 420 code (rear bank cat below efficiency threshold) is just a spurious signal related to limp mode.
Do a search, there is a thread or two on replacing the APP sensor. It's very easy to do yourself. As I said earlier, the hard part may be finding the part in stock....

Some guy explained the exact same problem when I was at the dealer buying parts =P
The staff there were like "Huh? Like it was running out of gas?".
I'd probably get a job at the dealer if I explained what the problem was like nfnsquared did LOL
