multiple problems, some fixed, some remain

Long story short, the turbo went out last week. replaced it with a td04 and she was happy again, havent had it re-tuned yet so its still on stage 2 lpt software.

I was on the highway earlier this week and had to accelerate quickly, in doing so i set off limp mode. tried resetting it but no luck. got it home and it threw three different codes. two pointed to throttle body (p1230 and another one) and one was a misfire (p1300).

Being that ive never replaced the TB and it has 186k i went ahead and swapped it out. replaced the plugs as they were badly fouled. still misfiring badly and throwing p1300 and p0300. i can see bad smoke coming out of the exhuast.

The DIC is a little more then a year old (brand new from saab) and the fuel pump was replaced at the same time.

I dont have a spare DIC to check, but could one really go bad in that short amount of time??

It is difficult to imagine the DIC went bad after just one year. And the codes for a DIC going bad are typically P1334 and P1312 as far as I know.

What spark plugs are you using?
