Get a can of STP Throttle Body cleaner and use it to clean up the IAS port
(back of the TB). I've had that problem many times (over a period of 39K
miles) and it cures the problem every time.
Check your vacuum hoses and make sure that nothing is loose as well. Also
check the CAP & Rotor since you have the MSD system...they wear out quicker
with the MSD. (If you don't believe me, check out the pictures of the Cap
and Rotor at 7500 miles on my site.) Code 12 is normal.

Subject: DML: Rough Idle
The last couple of days I noticed my Dak (97 V6 CC Auto) did not idle as
smooth as before. It would even die when at a stop light with the trans
in gear unless I kept the rpm's up. Mods added are a MSD 6A, Accel Super
coil, Quick D TB and intake, 180 stat, BW Select cap and rotor, and
magnecor wires. All of these have been on for at least 5000 miles and
never had a problem. I've checked all the connections and everything
appears tight. Tonight I got a check engine light. When I did the old
on-off-on-off-on routine the only code I got was a 12. I thought it
should end with a 55, but after at least 2 min. 12 was the only code. I
haven't had the battery disconnected in over a month. I even put the
stock coil back on and unhooked the MSD, but it didn't make any
difference. Any ideas out there?
