Oldest son texts me today that his car (1998 S420) is running rough and is throwing a CEL. Hmm. I get home and he starts it up. Sounds OK, but he points out that there is some vibration at idle and it seems to be a little sluggish.
I pop the DAS computer on it, run a full set of diagnostics, and the first thing I see is a P303 error. Ah-hah! Bad #3 coil. Weird brand coil on Amazon is under $30, but won’t get here until Saturday since it’s too late to make their next day cutoff. I dig into Advance Auto’s web site and find a store nearby that has one along with a new boot (most places sell these things sans boot, or so it seems.) Between a 30% off coupon and a $5 SpeedPerks coupon I have the whole bill is around $70 out the door. Get home, pop the hood, in under 10 minutes a new coil is installed and he claims it’s never felt smoother. He says he thinks it’s been going out over a period of time. I love those easy fixes. Coming up this weekend on the W126: Transmission mount, center vent vacuum actuator and new breather pipe and O-ring.
