does anyone know what to look for when you get an error code "P1357 front cylinder combustion intermittent" i had a problem a year ago a injection wire was broke but dont know what the code was then.
thanks

 

i had a bike in today the had a P1356 code on the rear cylinder, turned out to be the spark plug wire wasn't pushed all the way on to the spark plug. check your plugs and wires first !!!!!!!!!

 

This code sets when ION sense detects a lean condition. This could be for any number of reasons so you should know what to look for AND the best sequence for determining root cause.

1. Check plugs and plug wires. The ION sense function can be disrupted if you are using aftermarket plugs or plug wires.

2. Check for air intake leaks.

2. ALWAYS check fuel pressure.

3. If that doesn't resolve the issue you may want to look at the configuration of the motorcycle, certainly if the code first appeared after a change (air cleaner, exhaust, etc.). If that's the case, you may have a "lean spot" in the map that needs corrected.

Good luck!
