Title says it all... Been in the garage all day trying to figure out why it's hard starting and cylinder 6 misfire code keeps coming on. 2001 ram 5.9 gasser...Compression is great on all cylinders, I have done spark plugs wires and code still came on so I went and got a new fuel injector...light hasn't come on *Yet... drives great but there's a loud hissing sound coming from that injector... I sprayed it with water to see if rpm's would drop and they didnt... I went around the throttle body with starting fluid to see if it sucking air in somewhere but nothing... I'm sure it's the injector hissing, when I move it a little the hiss sounds is just a slight different tone but doesn't go away. Has anyone heard of this? Oh also i did check any symptoms of that plenom gasket and don't see any. Truck has 143xxx. Thanks!
