Default Re: 06 TSX Surging

Bob,

I own a 2006 TSX with a 6 speed manual that currently has 117,000 (mainly highway) miles on it. I had the same issue with my TSX at
70,000 miles. At first I thought it was my imagination, but finally I realized that it was not. I did 3 things: 1) I changed the plugs, 2) I switch
from Citgo premium to Exxon premium, and 3) I added a can of BG. After about 3 weeks, the surge went away. It eventually came back,
after several thousand miles, so I added another can of BG, and once again, it went away. Now at 117,000 miles, it is back. Needless to say, I
will be adding another can of BG soon. I also discovered that during a cold start, it is much more notable. I have a 50 mile commute (one
way), and when I get to work, and put it in 1st gear at 3,000 rpm's, it is much less noticeable, almost like it is not there. After the TSX sits all
day at work, once again, it is much more nocicable. I hope this helps.

Not sure what you mean by surging, but my first guess is your idle air
control needs some attention.

Tony,

Thanks for the reply. I'm now at about 90K miles. I probably should go
ahead and change the plugs.

In my case, with the automatic, there are two common situations;
1) Under light throttle the car will surge forward for less than a second,
then slow down, and repeat.
2) I pull out of a parking lot with a slight slope towards the street and
make a turn into the traffic lane. I give the car a bit of gas to get it
rolling, take my foot off the gas, and as I'm part way into my turn into
the traffic lane, I give it some gas to start accelerating and it stumbles
as if the fuel got cut off for a fraction of a second.

I never seem to experience this with cruise control engaged. This makes me
wonder if it's a problem with the TPS or whatever converts the mechanical
throttle movement to digital signals for the engine control computer.

I wonder if I might have a fuel filter problem, but I've never run the fuel
tank empty and 99% of the time, fill the tank before the low fuel light is
illuminated.

The Check Engine light is NOT illuminated and my mechanic says there are no
stored error codes.

I took the TSX to the dealership today. As expected, there was no code to
be read from the OBD port. They drove the vehicle and observed the problem.
They suggested replacing the APP(?), or what I would call the throttle
position sensor. I agreed since I never seemed to have the problem with the
cruise control engaged. After replacing it, they test drove it and said it
was much better. I returned their loaner TL, paid the bill, and drove off
with the car behaving they way it should. The bill says they replaced
37971-RBB-003: Sensor Assy. Total cost was ~$325.
