Acceleration issues
I have 2007 Dodge Ram 1500, 2wd, 4.7 v8 engine. Milage 106k miles
I have zero codes and no check engine light on. I have replaced my plugs with Champion double platinum, then all 4 o2 sensors with Bosch brand and all 8 ignition coils with MoPar Brsnd. Sometimes when I start truck up and try to accelerate there is nothing then takes off.
Just a bit ago I was going forward after backing up and I heard a pop sound and had zero acceleration and it was dying. I put it park and shut off and started back up and drove with no loud pops or no acceleration issues.
Would this be a catalytic converter problem or a map sensor? My catalytic converter upstream is black on bottom side.

My problem started after changing out all 4 of the o2 sensors. Ignition coils didn't help. What brand is recommended for dodge for spark plugs and o2 sensors?
