Getting a P1312 code on my 01 aero. Plugs were changed about 4k miles ago to BCPR7ES-11.
I'm wondering if I'm getting this code due to the plugs not being the $platinum$ or if my DIC is on its way out. FWIW, the DIC is 20 years old this year, and I'm guessing roughly 155k miles on it.
Also, and not sure if this is related, but floor it up a hill in 2nd gear, with lots of boost, and it will cut out for a split second, accompanied by a rather large puff of black smoke, then catch again instantly and take off. Doesn't throw a CEL when that happens, but the next time I turned the car on it did throw a CEL.
Here's the detailed report:

Anything else I should check before throwing down the money for an OEM Saab DIC?
