29CD Misfirings, cylinder 1
29CF Misfirings, cylinder 3
29CE Misfirings, cylinder 2
29CC Misfirings, several cylinders
Spark Plugs were just changed by the dealer about 5,000 miles ago, HPFP was replaced about 10,000 miles ago, and Injectors did not fall under the recall according to the dealer. Do you think the Spark Plugs would go bad that quickly? If I replace the Coilpacks would you suggest replacing all Spark Plugs as well? Even with the Spark Plugs being pretty new? Thanks!

My car just threw the exact codes. Anyone know what it is? I tried replacing the sparkplugs and coils. Codes still pop up, going to try bank 1 o2 sensors tmw.
