help please
2016 RT charger here
changed plugs and moved coil packs around still showing misfire
WHAT ELSE COULD IT BE??????
car sputtering bad loosing power

 

Still the same cylinders misfiring? Did you clear codes after changing plugs and such? Done anything else to it??

 

Yes moved injectors around and still shaky we cleared codes after a lil miles check engine light comes back on flashing a lil while then goes off( repeat )
any clue ?
still says cylinder 3
do u think need to check pressure in that cylinder

 

That would be the next step, yep.

 

What should pressure be holding at ?it’s holding at 124 no skip in it . What else could it be ? Wha

 

What do you mean by the pressure is holding? Do you mean that's what it reaches for a compression check, or were you doing a cylinder leakdown test? How does the reading compare with other cylinders? Compression and leakdown, unless they are completely unreasonable values, should be compared with the other cylinders.

Also, have you inspected the fuel injectors and wiring to make sure the wiring at least looks good and the connectors are seated on the fuel injectors? Does your scan tool have a datastream mode so that you can monitor the fuel trims on the cylinder banks and watch the voltage on the oxygen sensors?
