I can't find a good thread related to this issue so I'm going to post and if anyone find another thread please post it here! My 2006 to when accelerating seams to kinda get stuck at 1,500 rpms, and if I push the gas pedal a little harder it will jump back up to 2, usually around 40 45mph and it kinda vibrates a little, it's not crazy but noticeable. Trans issue? The throttle body is clean, or could it be a torque converter issue? I'm not sure!

What's the oil level in the engine like?

newlux

• Oils good! Just changed it and it had this issue when I changed it as well

2006 TL not to

I'm thinking something is wrong with the accelerator pedal position sensor.

newlux

Okay awesome I'mma do alot of acurazine research on that and see if it matches!!! Thank you my man. I wish somebody lived where I lived, I would pay that guy/gal to repair my car for sure. I have so many things I want done haha

newlux

You don't think it's a torgue converter issue do you guys?

newlux

Im seeing alot of things it could be, like throttle body or vacuum leaks or IAC fuel pump pressure, Mass airflow sensor, ect):

pohljm

what codes are you getting?

newlux

No codes): I don't have a reader for that, nothing up in the cluster, just more as a what's this and I don't like it let's figure out why it's this way thing.

Go to AutoZone and have the codes read for free.

What's the maintenance on your transmission? Sounds like you may need to change pressure switches and possibly look at a minimum 2x3 fluid change.

newlux

So the guy I had bought it from never changed the fluid I'm pretty sure, it had 100,000 miles on it when I bought it, I have changed it once and I'm doing a 3x3 very slowly.aybie even a 4x4 haven't changed the pressure switches as I'm confused by how many, locations ect. Even when I read about them lol I'm not the most savvy car person, but im learning!!

newlux

I can pull codes even if there's nothing showing on on the cluster?

Hold down map/guide - menu button & cancel at the same time for about 3 seconds. I believe a menu will come up where you can view all stored codes, dates and times. Click on XM(ECU) option and diagnostic info

If you want to test the APP sensor, see if you can engage cruise control and accelerate past 1500RPM.

newlux

Hows the slack? Good or bad? Does it need adjusting? I'm t


rying to just pull the sensor off and replace that but I'm struggling a little bit with that

Remember that awesome garage i told you about? https://acurazine.com/forums/3g-tl-p...sensor-730958/

How many miles does the car have? have you ever replaced any off the transmission pressure switches?

newlux

Pressure switches is my next endeavor, I tightened the cable and it didn't help unfortunately!

newlux

Mines an 06 and when I push the xm it does nothing 😰

newlux

I got a code! Ecm/pcm relation malfunction also too right of the tool has abs on it, how bad is that?

newlux

newlux

does anyone have the service manual page for the app sensor? i don't seam to have a service manual only the owners!

WDPanda

Any way to make a video of this hanging rpm? Sounds difficult to diagnose.

newlux

i can definitely do that! I did change the a p p sensor it still seems like it's there, but it does drive noticeably smoother now(: RPMs jump higher as well.

newlux

Sorry for the quality, but as you can see it gets stuck and when you see the rpms jump is when I pushed the gas a little harder.

WDPanda

When the rpms jump, does the car lurch as well?
what if you were to put it into manual mode and downshift instead of giving more gas?
any slipping during WOT?

newlux

No the car doesn't lurch at all! it makes a noise though, the best way to describe the noise is its a humming noise, like going from 0 to 10 mph but constant. Now don't hate me, but i have no idea how to use the manual mode, i cant even drive a stick! wide open throttle correct? Im not sure about that, any way to check? Just stomp the gas? You seam like you know your stuff i appreciate your help immensely. after changing the app sensor though the car has a much easier time passing 2,000 rpms (:

Went to auto zone because the engine light came on then started flashing the code reader said all 6 cylinders were misfiring and a couple of randoms as well. They said the fix was spark plugs. Ok stop back up when this all happened there wasn't a problem with the rpm. So I changed the plugs and it actually ran worse drove for about 3 or 4 blocks and it wouldn't get over 2000 rpm and 15 to 30 mph and would drive like it was over heating and would die after going a mile or 2 .let it cool down started right up and would do the same thing I even changed the coils still the same. Someone told me it could be the crank shaft positioning sensor but I can't find what the o6s look like or where it is exactly so I can't change what I can't find so annoying.that's what I got sorry for the long book.

What brand of plugs and coils did you put in? If you didn't use Denso or Hitachi coils and NGK plugs, then it might be time to start over; put the original plugs and coils back in.

El_Cheapo

Based on your video, it looks like you're in limp mode. You also have VSA light on.

The service manual is not very helpful in how to proceed. It only says to "Do the applicable troubleshooting for ECM/PCM".

You need to be clear on your problem.

Was the misfire your original problem?

Limp mode is the a new problem that only started after you replaced the plugs?

newlux

i can turn the vsa light off when i push the button, i turn off traction because i feel like my car grabs crowns in the road way harder with it on.

horseshoez

iTrader: (2)

Which transmission do you have?

newlux

Automatic(:

horseshoez

iTrader: (2)

When you say "grabs crowns" are you saying you have better control on a crowned road, or worse?

newlux

Well basically I mean I have less control with it turned on, what I meant by crowns is just bad roads, but my tires are junk so it could be that as well! I have sentury uhps lol

​​​​​​Ah I had the wrong understanding of what a crowned road was but Google helped😂

horseshoez

iTrader: (2)

Got it. I've never driven a non-LSD automatic TL on a bad road, but I can see how VSA might make control of the vehicle a challenge. On the cars with manual transmissions, the LSD works seamlessly on rough roads without the need to disable VSA; that said, I imagine the VSA programming is a bit different on the cars with an integrated LSD.

newlux

Makes me wish I had a stick and knew how to drive one haha
