Well I went by the dealer today to have them plug into the STAR DIAGNOSIS machine. Well I got lucky... I asked my service advisor (young, real nice guy) if he could just hook it up real quick and pull the codes. Well they rolled the machine out, and plugged it into the CAN/BUS under the hood (I did not know that the OBDII info could be retrieved via this port! I learned that the OBDII connector under the hood was simply the 'generic connector' to meet the basic laws of OBD).

Well, I was hoping to get some sort of pattern, but didn't get anything that really helped....

Got codes:
P0300
P0302
P0303

So I'm assuming that these are cylinder 0 (?), 2, 3 misfires. Anyways, I decided to go in and buy the coil ends, as suggested. So I purchased 3 coil cable plug ends ($11.76 x 3), and I bought 6 spark plugs ($2.69 a peice). My spark plugs were changed about 35k miles ago (my service advisor told me that they're supposed to be replaced @ 15k intervals.... I thought I remember the intervals being 30k... I'll have to double check.) Well I was past due, in any event.
While there, I also bought a new wiper blade because the BOSCH blades sold at auto part stores do not fit properly (even though they are the right length and suppsoed to fit my C280). Well that blade mechanism was $36.40! Jeeez! I also bought some of the MB Grease (he gave me bearing grease?)... I'm going to lube my wiper mechanism.

I am going to have my independent mechanic replace the coil ends and spark plugs on Wednesday. This is a pretty basic service, correct? Just spark plug replacement and a few added minutes to replace the coil ends... correct?

(I really hope that this is the end to my LONG and PROGRESSIVE ACCELERATION RESISTANCE!

Thanks guys.
