Misfiring hemi, wtf?

[IMaDad]

It started misfiring bad. I thought I lost the transmission with how hard it was lurching. Part throttle and low Rpms mostly. Leaning into the throttle makes it go away.

Any ideas?

Sounds like weak coils to me. I don't know how many the Dodges have.

Edit - looks like one for each cylinder. I'd bet one or more is weak and misfiring.

Can I ohm them out to test?

 

[Kyzrsoze]

You can. On my Ford when one is bad I can often tell by unplugging each one from the harness and seeing what difference it makes.

Btw why get mad at them when you bought a Hemi ?

Are you not aware a Hemi is 2 plugs per cylinder ? Has always been that way even the old Hemi

Only thing makes me mad is these are truly not a Hemi , when you take the heads off nothing is Hemi about them

The older is a true Hemi

You mean my Hemi is not a Hemi?? I would hate to see the gas mileage on a real Hemi!

My 09 150 was doin the exact same thing, low rpm it was stuttering until you poured the coal to it and it cleared up, now it's Only doin it 3k+ rpm, figured it's time to take to the dealer and let em rape me, cause I ain't breaking them plugs off

6 of 16 down.... I'm using two 3/8 universal joints for a 2" extension because I've lost mine.

It makes it extra fun.

To me these are really bad and dirty.
Thoughts?
