Missing & Sputtering
« on: May 31, 2009, 10:13:26 PM »

Hi Guys,

I have a 2004 Road King Custom with 28,000 miles on it.  Well maintained and stored in a garage.  Recently it has started missing and sputtering - running rough.  I changed the plugs - no help.  The manual says to change the plug wires.  Any other thoughts?

Injected or Carb?  Does it happen hot and cold? Is problem at idle?
Intake leaks are common.
Lots of other possible causes but go for the easy things first.

If there are no codes, I would check the intake seals and do a fuel pressure test.  On that bike it should hold pressure when you turn off the power.  If it drops to zero fast, you have a hole in an internal line.  Also, if it happens less with a full tank that's an indicator as well.

P0370 - CKP Sensor Intermittent
P1353 - front cylinder no combustion EFI
P1356 - rear cylinder no combustion EFI
and
suggested PN 32915-04.  Don't know what this part number is - will call Harley tomorrow.

CKP – Crank Position Sensor. The CKP generates an “AC signal” which is sent to the ECM where it is used to reference engine position (TDC) and speed.

It's fule injected and the plugs ceramic is clean & white - no caramel color - like it's running really lean.  The motor will idle for a couple mintues and then die.

Think this CKP sensor could be causing this?

Absolutely.  Without a good signal from the crank position sensor, the ignition timing will be all over the place and you will be lucky to get the engine to run at all.  Check the wires leading from the crank position sensor for damage.  It isn't uncommon for the sensor or the wires to be damaged when changing oil filters if the wrong type of wrench is used.

Don't worry about the part number that shows up at the end of the DTC check, that's just the number of the module and doesn't have anything to do with your problem.  It's just for reference.

Also if the sensor is like on most cars, it won't throw any codes, it just senses the crank revolution, so if it doesn't sense the crank coming around each time, it just doesn't allow spark/fuel. I have had to replace two on my truck, ran like chit!
