My 2002 is skipping (P0304) after only about a week with a new DIC. It was starting to have occasional starting probs too. The skipping #4 cylinder started just after I changed the plugs today. I replaced the NGKs with the same ones. I'm thinking it's the new DIC ( it a genuine saab DIC) but don't have an extra one I can swap out just now. ( at least til my wife gets home with the 'vert) Is it Ok to pop in a red DIC, just to see if it is still skipping?
