2017 PIU 3.7
Had shop replace water pump, timing chain, vvts, and all the rest. 5k. Took them 3x in a period of 2.5 wks to get it to run right. But alas, it's not. Before I could FOT at any point, regardless of speed etc and it would just get up n go. Now it blows codes misfire 4.5.6. There 5 versions of the Cyclone 3.7 timing chain setup they say they got the right one. They had to go back in 3x and it's still not right. I did see a coil pack on the ground and not with the others safely in a parts box. Didn't change plugs or coils. 2 yr warranty but wondering if they have the 456 bank a tooth of?? Anyone else has issues with this?
 






Welcome to the Forum. :wave:
Perhaps members who have done a DIY pump replacement can help.
