I have an 03 durngo with the 5.9 and im having random misfires on the entire right bank. Replaced all the typical ignition parts and even pulled and cleaned the fuel rail. Still happening. Not too noticible at idle but gets bad when I get on it. Typically barely existant until it warms up just a little bit. Running fuel system cleaner through helps but as soon as that tank of fuel is gone and replaced, the problem returns
have the same problem?
