I haven't done all my research yet but I've heard the AEM EMS eliminates this issue... the downside is that it's complicated and expensive, if you do it right (EMS, wideband, tune, maybe some gauges lol) you're over $2k in no time.
Hey are you the same MYFIRSTEVO over on socalevo.net?

hey have you tried the "creader" thing? i heard that it works.
also, will this limpiness damage the motor in the long run you think? or it's just a safety precautions that the ecu doing to protect the motor?

Haven't tried the creader thing, seems too hackney'd for me.
Oh and I just saw you had some stuff 4 sale over there, I think... correct?
oh yeah... hehehe... well i'm as depressed as a monkey without his bananas.
Freaking car is pissing me off.
how did you deal with all this problems man? i'm trying to learn more if the AEM EMS will actually get rid of this problems...
This sux cause most of the studdering issue happened on the 03 model, and mmna isn't helping either...

I've been having this p0300 problem for months now..I am so sick of it... I just keep my obdII scanner plugghed in, so when the CEL and misfire happens...I just delete and keep driving..until 20 mins later..it happens.
Thats why I have HKS VPRO standalone goin in 2 weeks. Just cant stand it anymore. I just hope the p0300 dosent affect the VPRO, since the vpro uses the stock ecu for cold start, immobvilizer and other small things..EVERYTHING else the vpro will control.

mobounce, what's this VPro you speak of??
HKS VPRO...standalone that installs like a piggyback, but is 100% fully tuneable! just like the AEM EMS, but better drievability IMO!! The only downfall...it is not user tunable, you must be tuned by a HKS sanctioned pro shop only... but, if you want to set and forget..the VPRO is awesome! if you like to tune your own vehicle, and tinker... AEM is the way
