05 Dodge ram 1500 3.7L V6 MISFIRE PROBLEM
On my 05 Ram, I am misfiring badly, I値l drive to work and when I get off it will misfire on the way home and I have to stay at super low rpms. Replaced the crankshaft sensor, I知 having P0300 random misfire code. I have a small exhaust leak near downstream o2 sensor, what should i do or replace? I replaced all 6 plugs. Not sure if I should hand over tons of money for all 6 coils. Please help!

the fluids are good, at low rpms it does fine, if I press the gas pedal down pretty good it stumbles and puffs

I would recommend checking fuel pressure with the motor reved up. Fuel pump might not be strong enough to keep up with fuel demands. Other then a fuel problem it could be a restricted exhaust like a plugged cat. It could also be a broken or weak valve spring but its a random misfire so i would check fuel and air first
