  1. So, I cleaned the MAF as a preventative measure, changed the plugs and re-checked my coil connectors. The last 3 days there have been no misfire issues and no codes. Car has run smooth and powerful. Cross your fingers, but I think it's solved.
  2. Ha! I know exactly where it's at. I checked to see if it was tight. I'll give it a clean-up as well...
  3. I did check the coil connections this past weekend. Cleaned the connectors with contact cleaner and made sure they connected with a nice "click". Pulled the boots back to verify that the tab was locked in place. The original plugs were tight and looked good (nice color and correct gap), but I just picked up some Bosch FGR-6-KQE to replace them just to be sure. So my next step is to clean the MAF, replace the plugs, and R&R electrical connections associated with ignition.
  4. I've ordered the plugs and will change them out. They looked just about perfect for 7K plugs, but it can't hurt. I did research the fault codes and looked back at Misfire guide, but it pretty much tells me to look at what I already replaced (aside from the plugs). The new code was the MAF code and I plan on cleaning it this afternoon after I pick up a set of security torx bits. What does "signal implausible" refer to? You are right about the Durametric... I really need to spring for one, but I only have Apple hardware. They need to come up with an Ipad app!
  5. I have a '99 C2 with 67k mi. that I've had for about a year. The 60k service was completed by the PO. I had an initial cold start misfire problem which resulted in a CEL with codes P0300, P0301, and P0303. Obviously it would run rough and if I could nurse it through the misfires (approx. 30 sec), it would be fine the rest of the day. Smooth through the RPM range and no codes or start issues. I did some searching and ran through the misfire trouble shooting guide. The plugs look perfect, coil resistance within spec, but I found cracked coils, so I replaced all six. I cleaned all the connec
