What is this po300 code?? From what I've read, it seems to cause the car to stutter and have the check engine light come on?? My car is showing the same syptoms, I always just thought it was a bost leak? I haven't gotten around to getting a boost leak check done yet, so I'm just curious...

The code is a "random/multiple cylinder misfire" code. There is an updated PCM flash the dealer can do, but you need to make sure that your car isn't actually misfiring first. The flash fixes the code 'ghosting", or setting for no reason. If you really have a misfire the flash won't help any.

It should be under warranty, however, with mods it's usualy 50/50..

Thanks for the info..

The mods should have nothing to do with the reflash, it is a known problem. Is your car actually misfiring/running rough? Just go to one of the "mod friendly" shops.
