Guys.

I think you remember about 6-8 months back... I posed a question about this momentary 'lull' that appears when you immediateley floor the 6-speed CL-S. Most of you apparently have experienced it and have found it quite perplexing. Well...
I think I have found the solution... well, at least it worked for me!

It's the TPS. During my experimentation (albeit destructive in many cases!), I had to remove and notch my TPS. I found that the problem is eliminated by twiddling with the TPS and repositioning it slightly advanced. You might have to 'notch' the TPS because it only has so much adjustment range. Don't go overboard... or the car will run strange!

Now... floor it at 2K-3K RPM in 1st gear and it spins to redline!

Enjoy...!!

Thanks for the tip. Which way do we turn for advance? How much movement? Should I buy a Helms before messing with this?

What is TPS and where can I find it.

I have a 03' 6-speed and feel the lag you are talking about. please post some pics and specific directions. I have a limited knowledge of my car under the hood. sounds good. what effects will this have on other parts of the engine. what is it actualy fooling the engine into doing for more performance. does this add hp or better throttle response

thanks

I am RobG

TPS=throttle positioning sensor

jproy

I hope and think that I am correct.

TPS= Throttle Position Sensor

I think it is located on the throttle body.

I'll have to put everything back to stock over the weekend, so I'll take some pics then.

Some things here:

(1) You won't gain ANY hp or torque... nada!
(2) I wouldn't recommend 'notching' the TPS like I stated before... warranty issues etc.

I still haven't tried this on a stock Throttle-Body... so wait until the weekend.

TypeR... wait a tad on your efforts, if you dont mind

Is this something the dealer can/would do to correct this problem?

hey allmotor sounds good but my car has the esm for the blower so i dont know if i would adjust it.what do you think? if i adjusted the tps would that effect the esm?

Good deal allmotor....shoot some pics and let us know a little more...I would love to get rid of that lag if it doesnt damage anything

Is notching the TPS something that the dealer can
use as an excuse to void the warranty?

allmotor_2000

Yeah... if you are concerned about the engine/drivetrain warranty, don't do anything with the TPS.

The TPS bolts don't have a screw-head... hence in order to unscrew/remove the TPS, you have to either drill through the screws or notch a line for a screw-driver. I don't know if the dealer will notice that... but notching the actual TPS... they will
surely find out.

Ehhh O well...I guess i will not be doing this...but thanks for all the work allmotor in trying to fix this problem

What lag? I don't feel it. Or maybe I do, & don't notice it, & think it's normal? What RPM in 1st? When I slam the gas in first, all I get is tire spin
