Volvo Penta-3.0L GLP-J/SX Drive 2009 37 hours
All,
Series of events:
1. Last night, I got a wild hair and decided to look at the spark plugs. They all looked the same, sort of brown and clean. No rust or oily deposits.
2. Today, I decided to run the engine. Ran fine until it got warm. Then, a serious misfire at idle and eventually stalled.
3. I noticed a "snapping" noise in the engine compartment. Upon looking, I see spark jumping from the spark plug wire boots to the head on cylinders 1 & 2.
With that, I am finding it hard to believe that the wires are shot at 37 hours but I can be convinced.
My plan:
1. Replace plugs with OEM-MR43LTS (AC)
2. Replace Wires.
3. Replace Cap/Rotor
I will only use OEM Volvo Penta Parts.
I can only think that the misfires are due to plug spark jumping. All other speeds are smooth.
Ideas? Thoughts?
Am I on the right track? What else could cause this? My experience (automotive) tells me that arcing spark can definetely cause and idle issue.
I thought it may be the carburetor until I saw the spark issue.
Thanks.
