titaniumkingpin is it a custom tune or is it a mail in? i'm on a mail in right now and it's every few thousand miles. if it's something like every 3-6 months, then i can live with that

 

im on a mail in flash

 

I get this same problem. I used to misfire at least once every single day, during idle. I also had HKS cams (272/272) and DynoFlash... however, my misfire was happening before and after the DynoFlash very oftenly.

The very weird thing is... after replacing my crankshaft, clutch, and flywheel... the misfires went away for the most part. I get a misfire at idle maybe once a month now... and it used to be literally every damn day... all at idle.

 

I am on a stock P300 flash and got it at idle

 

I had gotten this code a couple times in the last year, but it went away on its own. I just had cams and a mail done in the last week and now it is throwing the code every day, no drivability issues that i notice though. I dont now whats going on, any help would be awesome.

thanks

 

Does the Dynoflash raise timing at idle to get the cams to idle better? I added timing at 1000 rpms with my emanage and started getting the P0300 at idle. I started with 15* added in and dropped it to 12*. The code came less often at 12* but I would still get it. I will be dropping it some more as soon as my coilovers get back from being rebuilt and my car gets off the stands.
