1997 dodge dakota need help missfire
I picked up a 1997 dodge dakota 3.9 with 180k and it has a random missfire code p1391
It is running like **** sounds like its running on 3 cylinders backfires threw the intake when u give it gas sometimes The guy i got it from said he changed the
Coil,crank position sensor,cam sensor,distributor,map sensor, and a new Computer and a ton of other things what else could do this i have looked around it is a common issue but cant seam to find anything.

He gave me the old pmc plugged it in still no rpms gauge even with the new one still doesn't work i think this is somehow connected with it not running right will have to dig into it more tomorrow.
also the guy replaced the whole distributor how do i know if he put it back in the right spot or not is there a way to check? also want to check the timing chain how are the marks suppose to line up?

He pulled the distributor and screwed up the fuel sync. That's why it's running poorly. Let your dealer reset it with a scan tool. It's the easiest and fastest way.
P1391 is not a random misfire code, it's a loss of cam or crank position sensor.
Make sure that OEM Dodge sensor have been used. Lots of the aftermarket ones are garbage.
