x2 on the fuel sync

 

The truck actually idles really well but has stalled a couple times in the last month, its a dog up to 1,800 rpm then it feels like it jumps to life the mis is very noticeable and runs better with the O/D Off. Runs the same Cold as it does warm, I'm in arizona sun shines year round.
Ohh somebody said cranksensor, I've already replaced it

 

Do you know any thing about this? I think my cam sensor has gone haywire my mechanic said the timing was off and it was an ignition problem? If it makes a difference I swapped out the kegger for the F1 air gap awhile ago I've heard our trucks have death flash that throws the timing off a few degrees when the plenum blows instead of fixing it the right way since I replaced it no need for a death flash right? I wondering if I just need to get the pcm reprogramed, just throwing ideas out there

 

I would try a new cam sensor and reset the fuel sync manually (I don't have pic right now). Eventually, get it set by a mechanic with the correct tool or the dealer.

Get a mopar sensor.

 

Cam sensor has nothing to do with ignition timing, it deals with injector timing only. So, if it was that far off, you would have an issue with EVERY cylinder, not just two..... Still and all, replacing it sure won't hurt, provided you get a sensor from the Dealer. If your crank sensor is some aftermarket part, replacing that with a dealer item as well, is going to be a necessary step in troubleshooting. Our trucks REALLY don't care for aftermarket sensors in critical locations.

 

5.2, 5.9, 4.7, 5.7 or 8.0 ?


It's setting 6, 8 and multiple. You need to be looking at why just those 2 specifically. The multiple is caused by the condition that the 6 and 8 are creating. Ignore the multiple misfire.


Tell me which engine and we can go from there.

 

Sorry I left out some pretty specific info it's the 5.9

My truck is also backfiring up into the intake manifold alot so bad to where it was poping the caps off my intake manifold (extra vacuum nippes), that is what has lead me to believe it was a fuel sync issue

 

Is there anyway Ill be able to determine whether my timing chain is the issue without turning any wrenches???

 

Check compression on #8 with #6 spark plug out and see it if goes lower. Or vice -versa.
