LW flywheel leading to throttle problems??
 

For those who are using a LW flywheel, I'm having an unusual throttle problem. When I come off the throttle above 4000RPM, the throttle seems to hang a bit before the RPM's begin to drop. I've tried cleaning the TB and disconnecting the battery to reset the computer, but the problem persists. I've been driving around with the FW for about 2000 miles now, and the problem is just emerging. Any thoughts?

That has nothing to do with your LWF, as the less inertia you have, the revs will fall quicker, not slower. Not to mention, if the problem just started, and you've had the LWF on the car for a while, they're not related.

Car year and mileage? Cable or e-gas?

2000 box s, 143,000 miles.

tip or manual?

It's a 6-speed that was just rebuilt this winter. Guard torque-biasing diff was installed, along with new 2nd gear synchros and the G-Box detent...and the LW flywheel and a Spec stage 3-plus sprung clutch. Also added the RSS underdrive pulley.
This throttle hang-up thing is kind of a mixed bag. around town it's a bit annoying, but for AX or when I'm just really getting on it, it almost sounds like I've got a sequential gearbox.

Ok it should be an e-gas car. Possible throttle position sensor at the throttle pedal, or failing throttle body. If you have access to a durametric there are tests you can run to narrow it down. Any pending error codes?

I do have the Durametric software (I got it with a Softronic Reflash) I also have had a CEL, code 0140, but I thought that was simply a failing post cat O2 sensor.
