So this has been a Paine in the *** for 6 months
to start it's a 1998 durango 5.9l it just started one day it feels like a misfire shake on light acceleration or sometimes just lightly crusing on check lights ever no codes I've changed plugs 3 types, cap and rotor brass, 8mm plug wires, both o2s, intake manifold gaskets, crank sensor, cam/pickup coil,
injectors, tps ,iac ,iat,fuel pump ,compression test was 125 +/- 5 on all cyls f me right? Any ideas

 

What kind of plugs did you use? Anything other than plain old copper cores can cause issues.
