Bogging and Hesitation on Acceleration

I have an 05 TL 6 speed. I notice a lot of bogging and hesitation while accelerating especially at lower rpms 2000-4000. It is most prominent in 2nd-5th gears. When ripping through gears it doesn't seem as bad but it does happen a lot. Any one have any ideas on what this might be?
Thank you

Perhaps a clogged EGR valve? No MIL?

Would a failing EGR valve cause emissions failure? I just got my emissions tested and passed.

High mileage? As the other poster said, no Check Engine Light?

My car has 78000 on it but this problem has been occurring for well over 40000 miles... it just seems like it has gotten a little worse. And there is no check engine light.

APP-- Accelerator Pedal Position-- sensor going bad, perhaps.
Not uncommon problem; there are several threads about it.

I tried looking for this subject but didn't find much. No that it's warmer and I am using the A/C it seems to be even worse. It feels like there is no power and it is obviously surging and it almost feels like it's missing.

Run a search in 3G TL with "APP pedal sensor"-- you'll get 72 threads, many of which apply, including https://acurazine.com/forums/3g-tl-problems-fixes-114/app-sensor-replacement-what-do-before-doing-830989/ and https://acurazine.com/forums/3g-tl-problems-fixes-114/app-sensor-replacement-question-818110/.

Hope that starts you off in the right direction.

I'm sure you would have probably noticed this and it's very low probability, but I had a similar symptom with a broken brake switch light.... the light mount was cracked making it misaligned (dealer tech cracked it replacing the dash on the cracking factory replacement program).... so the brake light was on / passing the brake applied signal to the ecu all the time... ecu modifies everything expecting idle power and slowing... so frequent odd hesitation, esp mid rpms on acceleration....

My car is doing the exact same thing. I should have an APP sensor in a couple days. I will let you know if this fixes it.

Thank you
What gas are you using? ping could lead to massive timing retard and feels like bogging/hesitation.

alex2192- I had no bouncing revs issue. The car would just fall on it's face between shifts. I got the APP sensor installed this weekend. I haven't gotten a lot of miles on it yet but so far I haven't noticed any hesitation issues. Could be in my head but the throttle response seems to be much better also.

Same issue

Hi. I know its an old post about the acceleration issues you were having with you TL. It sounds similar to whats going on with me. Did you ever figure it out. Thanks

instead of asking if the OP ever solved his problem, LIST your problems!
this way; we can run through our mental check lists to see if your car is suffering from the common problems, like clogged EGR valve, bad APP sensor, etc.etc.etc.


in other words; car problems are very unique. you could have a different problem then the OP.
and is also how you troubleshoot...by running down or listing known symptoms and double checking and cross checking with known problems.

Ok, I can do that




I have a 2004 acura tl 6 speed. For quite some time, Ive had this issue where the care intermittently losses some power. It is subtle. Kind of like the loss of power you get when you turn the ac compressor on. Just not the same responsiveness compared to other times when the car seems to be working It can do this for a few minutes, or longer. There is no relationship with ambient temperature. Does it in summer or winter. I have changed the following things so far




1. APP sensor

2. PCV

3. IAT sensor

4 New Battery

5. New spark Plugs




With exception to battery, everything is OE. Ive had no CEL or any stored codes so far. Any suggestions on what this may be?. Thanks
