P0312
Hi All,
Took out my S600 for a romp today after filling it up and dropping in a can of Techron and 4 ounces of OctaneBoost in my tank. Car ran really well for a nice ride at a steady 70. No misses, no bumps, no nothing. Just smooth as silk.
So of course I decided to step on it hard. I ran it up from about 45 to 105 mph mostly second and third gear. Right at 105, she threw a miss and a CEL. When I got home, I checked codes and had a P1170, P0300, and P0312. Cleared the codes and restarted and so far no problem. I will report back in a few days if the CEL returns.
New coil pack from Clark on that side and a new VT on top also from Clark.
