Keep getting trouble code P0356 after swapping 4.8 ... anyone ran into this code... I tried changing out coil on # 6 cyl,,, still getting same issue
funny, i just had the same issue on that tahoe we did a conversion on, just two days ago.
we swapped the coil and it fixed it. we did check continuity from the pcm to the coil and thru the coil harness.
be sure ign and ground is at the coil as well.
if none of those, possibly bad pcm driver.
I checked all the continuity on wires,,, everything checked out.. I cleared codes and swapped the #2 and #6 coils... If the code appears again I am going to get another PCM...
