Someone advise me to plug in a creader to eliminates the studdering issue of a p0300 error dilema.

my question is, is it a good idea or not? what negative effect will it bring upon the car once I leave this "creader" plugged in at all time?

Please advise, I'm running out of idea on fixing this studdering p0300 error dillema!

Thanks all.

I'd rather not leave it in since other codes "might" pop up and you won't be aware of them since its plugged in all the time. I just put my Creader in my armrest storage compartment and use it when i get a CEL.

From my understanding is it doesn't interrupt the CELs from being reported, what it does interrupt is the check cycle that the ECU makes to look for random missfires. So for instance, if you had a major sensor malfunction that resulted in that sensor no longer reporting to the ECU, the light will still going come on whether the creader is there or not, but it will interrupt the P0300 check cycle so that code can't come on anymore.

Again, this is only from what I have vaiguely gathered from various posts, not necissarilty fact.

In short, if you're looking to rid yourself of reoccurring misfire, the C-Reader works.

that and it works great, had on the car for like 2 weeks now, no misfires or studdering whatsoever.

had one CReader die on my, ordered another and installed, haven't tried warranty w/e-bay seller yet

I will have mine by Friday I hope, will report back with short and long term reports.

Where can I get one. I've been fighting this on and off and am tiring of it. Mostly after I've run the car on long drives 2 or 3 hours of consistent driving, usually always on the return trip. I get the P0300 misfire.

Ordering Thanks.

driving with it for about 15K miles......NO PROBLEMS! Good luck!

Does it HAVE to be the CReader brand code reader to prevent the P0300 code? I have another brand reader, and I guess I could just try it...but I thought maybe you guys could save me the trouble.

I don't know if it has to be the CReader brand, but with this brand, we know that it works. We also know that at least some other brands do not.
