I have a 2007 dodge nitro heat 3.7 v6. so my car started idling rough and shut off. I tried to restart it and it would kinda start but immediately shut off. if I put it in neutral and rev it at 2000rpms it would stay running but as soon as I let go of the gas it would chug and shut off. after a couple of minutes, so I changed one fuel injector with it just stop misfire but still shake and not stable on idle .no misfire shows on scanner monitors,.. does anyone have any idea what is going on?

A faulty idle air control valve?
Faulty throttle position sensor?
Possibly a weak or faulty fuel pump?
Just tossing ideas... 😕

Intake leak?
Low fuel pressure?
Worse case…bad head gasket/failure
OR in my last case on my 3.7L…valve seat dropped causing the valve not to close all the way, which also caused the rocker arm to drop
Here is a picture of mine when I had to get it fixed:
![39881]( "39881")
![39882]( "39882")
Easiest way to find out if this has happened… remove the valve cover and check all rocker arms. Or do a compression test

i put a scanner on it many times no codes given it seems to be the same problem many people have with the 3.7 ive changed spark plugs cleaned s few sensors changed oil changed tranny oil changed serpentine belt and pulley ect ect ect It only gives me rough idle sometimes when stopped at lights after driving a while full operating temp , drives very good . I cant find issue
