code p0300 Multiple cylinder misfire

Post by speedracer » Tue Nov 22, 2005 9:23 am

What the hell causes this? Plugs, crank sensor? I did have my crank sensor changed about a month ago (the old one went bad). New one worked fine. What about water in the intake? Help, I'm getting married and I'm too po' to take the car in for serive. Paul. :cry:

Did you put the SMT6 in yet? If so I've got some ideas that might fix it.

no, haven't put the smt in yet. I've been draggin' my ass about. Still waiting to install the tti long tube first I guess. Although, the code hasn't come back since that one time.

Connector on the side of my coil pack was loose when I threw that code. Whoever had it must have had a hotter coil on it, then sloppily switched back to stock to sell it. Took me friggin forever to find it because I had just changed the plugs and that's the main place I was looking for screw-ups.
