Coming home from work today, after some spirited driving, I noticed at a stop sign the car was idling somewhat rough. It continued only at idle all the way home. There was no lack of power or miss fire at all, just jumpy when stopped. Its giving code p1423. Thanks in advance for any response.

Thanks again. The code comes back to secondary air pump. Seeing as it runs only on cold start ups for short periods, I don't know how it would give it a rough idle. Would unplugging the maf give me an indication if it were bad?

Or mods or recent maintenance. again apologies for being lazy in my initial post.

Thank you very much, I'll check the fuse first thing. Then run down the list. Thanks for the explanation, I was confused how one was related to the other. I will locate the fuse and see where it leads.
