I think mine is busted. Do I really need this? what would be the result completely removing it and making a block off plate?

Thanks

 

People take them off or bypass them all the time. There's many threads about it...

 

wont your idle be too low if you block it?
mines bypassed right now but still sucks in a little air even if the white plastic screw is screwed all the way in...
in fact...my idle is a lot lower now that i tightened it all the way

 

The car will run just fine without it.

Just block the two "in" and "out" holes underneath the throttle body with some silicone sealant.

 

Mine is blocked off. If you just disconnect the coolant hoses, your idle will stay high.

 

Thanks guys.. i filled the vaccum holes with sealant and fabbed up a block-off plate for extra insurance.

 

To ask the dumbass question:

Why? What is this supposed to accomplish?

 

it does not accomplish anything ... the FITV raises the rpm on the engine during cold starts to help warm the engine up to normal operating temperatures... I would not like to be without it. When the engine warms up a little thermo wax plunger plugs up the hole and the car idles at normal 750 +/- 50 rpms...

 

I have a 1997 Y8 (OBDII) with the OBD1 conversion ECU and harness, ever since doing this my cold starts sucks ***, cams liek a bitch (old hotrod sound) until about 10-15 seconds have passed and it smooths out some, but still lobes alot...what can I do?
