So basically you fixed the oscillation problem by not doing anything? I don't get it.
So what if you ever need to reset the ECU in the future? How would you fix then oscillation issue then?

i have to admit, when i had the TB on my car, i never had an oscillation problem

i unhooked the negative terminal....removed the stock tb, installed the 1zz TB with the gasket maker, let it sit for 20 or 30min to set up

then i started the car and let the engine idle for about 10-15min then went for a spin...

never had a problem...

A change in airflow is a change in airflow. Theres no way you can really trick different air flow.

Re-install went well with not vacuum leak this time. I let the gasket maker sit on the new TB overnight and it sealed well. WOW! you can really tell this gives you significant increase in the mid-range and top-end. My car really takes off from about 40mph to 60mph.

New Problem: CEL


I've disconnected the battery for the night so it will reset the ECU. I'll give it another try tomorrow.

Any suggestions would be appreciated.

Might i also suggest pumping the brake pedal to accelerate situation of removing power from your vehicle. Once brake lights no longer illuminate, voila. You can reconnect the battery terminals again.

will this give a decent upgrade in the power dept? or is it more of a throttle response perk?

T-sport - you're a FREAKING GENIUS. I never would have thought of that.

Thanks!

Somehow the post got removed.

T-sport stated that you take your OEM TB, lay it next to the 1zz TB on the engine, unplug the 1zz and then plug the harness into the OEM TB, turn the car to 'on' but don't crank. Leave it for a few minutes, turn car off, re-plug the 1zz TB.

This, he says, will 'trick' the ECU to thinking the OEM have been reinstalled and fix the CEL. I haven't tried this yet, but it does sound smart.
