leo67 Posted April 3, 2005 Report Share Posted April 3, 2005 anyone experience a code po300 after the install of a tune,, did the re-learn thing that went smoothly, so far everything is running well, much better idle quality, driveability, etc. so i'm just confused on why it would set a multiple misfire code..

vtodd82 Posted April 3, 2005 Report Share Posted April 3, 2005 many people get that code after installing a new tune. who did you do your tune through? if bryan at pcm4less did yours, he will take care of it. he just needs to open up some parameters a bit. he fixed me right up. dont worry, its not a big issues at all. just give your tuner a call.

leo67 Posted April 3, 2005 Author Report Share Posted April 3, 2005 My first thought was to give bryan a call, but I'll wait till mon. ,, so i went and bought a scanner, cleared the code, and see what happens next, so far no mil, i'm hoping it was just a glitch/one time thing.
