I have an 05 chevy silverado 4x4 and we just rebuilt the trans and now i have a surge sometime when i come to a stop it levels itself back out and it's throwing p0300 engine misfire code, but it runs fine pulled the plugs they look great, the thing is i swear i remember seeing a vaccum line on the transfer case, but i can't find it, would a vaccum leak cause this, cause i have tried to tune it with hptuner by messing with the IAC steps and TPS and other misc stuf and nothing levels it out, but it does help it a little
