2005 ram 1500 4.7 80,000 miles on it. I have a P0300 random missfire code and hesitation when you give it gas.No one seems to know what the problem is. I have replaced,
pcv valve
map sensor
mass airflow sensor
both upstream 02 sensors
new plugs
new coil packs
iac valve
tps
new fuel pump, coolant temp sensor
acts like its not getting enough gas,engine light blinks when it wont hardly run. HELP ME!

 

Engine lite blinking indicates a misfire.

Does it run any better if you leave the front O2 sensors unplugged? (I think there are two of them..... I think......)
