Hope one of you has some idea what this may be.....

Driving an '02 TL-P w/o Navi, 64K miles. Since I bought it 2 months ago, it felt during moderate acceleration (to about 2700rpm) that the engine seemed to chug or lurch a couple of times while reving up. It was not as noticeable when stepping harder on the gas. I was really hesident to test the cars performance limits and tried reeeeally hard to limit my spirited driving until I knew what what was wrong.

Threw in a bottle of stp fule system cleaner but no difference so I kept going.
Changed the stock (and thoroughly cloggged with bugs and debris) air filter a few weeks ago wiith the K&N drop in filter and wow!! The car was like a bullet....responsive, reveving up smooth and quick, and was suddenly really fun to drive.....

...But now it is starting to chug again....right after the shift, it kind of bounces or hesitates 3 times before setteling in to the rev range over 3000rpm

Havn't checked the tranny history but it's shifting good for now....sometimes a bit hard....some recient delay before engaging from park.

Any ideas????
BTW, love the web site!! Go tl.

 

when mine feels a lil hesitant i change the tranny fluid and it feels much better right away.
but there are problems with our trannies so u never know.

 

I don't even want to say the T' word.....hopeing it's something simple like an o2 sensor or clogged something or other.

 

Its the Tranny fluid change it and it will go away, it worked for me.
