We moved injector from 7 to another cyl. Yesterday we changed valve springs. When you get after it the light comes on, then sometimes it will miss at idle and sometimes not. It does have the tick. Not sure what direction to go now.

How about an injector noid light to see if wire to the injector is bad? 1970 Plymouth Barracuda 1994 Ram 1500 4x4 5.2L 2004 Ram 1500 4x4 5.7L Quad Cab

This engine had been apart previously at another dealership and it looked like they drug the head across the floor scarring the deck surface. You didn't mention it being apart previously but it could be something similar. Get a combustion gas detector kit that is used to detect combustion gasses in the cooling system.

Another thing could be the intake runner change from short to long or vice versa. I wonder if soot in the intake will cause a sticky spot? Lean or rich condition maybe. I know nothing about the VVT system just spit-balling here. 1970 Plymouth Barracuda 1994 Ram 1500 4x4 5.2L 2004 Ram 1500 4x4 5.7L Quad Cab

I'm told that the cam timing is advanced at low rpms and retards as rpms increase. A rapid acceleration may result in a "lag" in the cam timing, resulting in an erratic signal from the cam positioning sensor. Why only cyl # 7 is affected, i'm not sure.

A rapid acceleration may result in a "lag" in the cam timing, resulting in an erratic signal from the cam positioning sensor. Why only cyl # 7 is affected, i'm not sure. I would think this is not the case as it only is affecting one cylinder. If it was something like the VVT it would affect other cylinders as well. Now having said that this engine is an MDS engine correct? I don't know what cylinders the MDS kills but there are four separate solenoids in the valley that control it, there could be a solenoid or harness problem if #7 is indeed one of the cylinders it kills.

Either way unless you are the original owner and it's still under a powertrain warranty I doubt Chrysler will help but you would have to run it by the service manager at your dealer and see if the district rep may help. Let me caution you though that if you are not a good customer at that dealership they may not be inclined to do anything. But keep in mind the magic word, please. It can't hurt to ask. Good luck.
