I have been doing lots of reading along with the fsm and can't figure this out. When the cruiser is idling it goes from 6.25 rpm and drops to 5.5 rpm(than catches and bumps back to 6.25). Also occasionly drops down to 3. Prior to this I had a code 71 but resolved the problem. The wires, plugs, cap, rotor, fuel filter, belts have 15k on them--all oem straight from Dan. I checked the resistence on the wires and all are with in factory spec. I also pulled all the plugs--a couple have a brown tint on the top white part but aren't really fouled. The air intake hose is new. I have pulled the plugs 2x with no change. I'm starting to think fuel injection. Also if I put my hand close to the exhaust it surges like it is missing. Any other ideas?
The cruiser has about 147k with all pm done at 132k except for the phh.
