Hello everyone, looking for some help on my hemi has a single cylinder #5 misfire here is what I have done so far...
Changed plugs on #5
Swapped #3 coil to #5
Swapped #3fuel injector to #5
Pulled valve cover look at #5 intake valve but seems to be moving up and down like any others have not look at the exhaust valve on that cylinder yet..
The truck misfired at idle and loss of power.
And yes I have check for power at coil and injector
Thanks

 

Compression test.

 

I will try and do that tomorrow need to find one to borrow thanks for your quick reponse

 

Do you have any valve train noise ?

 

Yes i do she has a little tick sounds like in the center on top of the engine

 

Continue with your compression check as HeyYou said and let us know.
If your tick is louder than the normal hemi tick 😁 investigate that further. Research camshaft and lifter failure...sorry to say. Some good posts here.

 

My 2009 had 92k on it when it suffered the same symptoms & resulted in bad cam / lifter. Did the work myself for about 800 bucks.....pretty aggravating......

i had the same problem. turns out its sticking lifters wearing out cam lobes.talked to dodge who admitted the lifters were faulty in the 5.7,6.2,and 6.4 and have now been changed in newer models.i think it should have been a recall since so many hemis have this problem

 

Any idea what model year they went to the 'new' design?
