Question about 2007 Dodge Ram Truck
I have taken my truck to dodge house to check the motor, they say nothing is wrong with it. When I have the truck in park or when stop in drive the motor is idling very rough you can see the truck shaking. Last night I got out of the truck while it was runing and you can hear the noise through the tail pipe. I sounds like it is missing it is getting worse it almost sounds like it is loosing compression.
I have all of you guys problems for roughly a year and half. Last week i decided to solve the problems. 1st i did all the electrical check (spark plugs and coil packs) it was find. 2nd i did the fuel injections (it may be bad and stuck at open) it was good. 3rd i did the compression check and the #6 cylinder was bad, it only got 60psi instead of 180. Finally i removed the valve cover and found the problem, the INTAKE VALVE SPRING BROKE. The reason why the truck was still able to drive with all of you guys problems is that the valve spring broke at the bottom (1st loop from the bottom). Even though the spring broke it was still strong enough to create some compression pressure in term no engine light.

I am currently driving a 2007 1500 fleet vehicle with the same 4.7 V8. Excellent engine, good fuel economey, and well running - except : exactly like your engine, it begins to miss after at idle for more than a few minutes. Learned to accept this - does not seem to hurt anything.
