i know there countless threads on fixing a bad idle, but im going through all the motions with no luck... im wondering if i just unplugg the fitv and drive around with it like that, will something bad happen? my car has a pulsating idle nomatter what i seem to do. ive tried everything and the only way it idles good is with that thing unplugged.

 

YO!

Check timing, fuel pressure, vacume and make sure that all your plugs and wires are tight and in good shape.

Timing -> verify that the timing is within spec
Check fuel pressure -> proper fuel pressure is read at the fuel rail, not the filter
Check Injector pulse -> take it to a mechanic...unless you have a Noid light set
Vacume -> make sure all your vacume lines are crack free!
MAS Sensor -> make sure that your Mass Airflow Sensor is working properly

There are many things that cause bad idel...you gotta eliminate them 1 at a time bro

 

This may help even more then I did originally...
