what vehicle? your 4 runner?
on a 1FZ it makes it run a little rough when cold, if its a 96 and newer if it has a code it will not pass emissions in most states, other than that really no effect

To quote the following document:

I had that code for a few months. During that time, I passed emisisons fine (after clearing the code and before it reappeared) and experienced none of the above symptoms. In my case the VSV quit operating properly, so my EGR was active all the time. My EGR modulator was fine though, so the correct amount was metered. The EGR just didn't shut off for cold starts, idle, and heavy acceleration.
Depending on why you have excessive flow, you may or may not have the above mentioned symptoms.
