    Northstar engine miss

    ok need some help !!
    Got a 2002 Deville Base. I have had a bad ICV for about 2 years now. It was real intermintent. In the passed 2-3 weeks it has really started to act up. I was planning on changing it this weekend,now this morning it started to have a real bad miss.Plugged in the scanner and pulled a P3008 code and also codes for the ICV.Changed the ICV and figured I had just fouled a plug. Changed all plugs (man was it a pain in the a?? to get the rears) with new ACDelco's. Fired it up and took it for a test drive and its still missing. Scanner is still pulling the 3008 code.Got me stumped !!!

    Don't double up on your posts. It confuses everyone.

    Your question has an answer up in the identical thread up in Deville. ^^^
