I woke up early this morning to go for a ride in the hopes I could get in a few miles before the predicted rain in the afternoon. Well I start the bike and it sounds like it's idling really rough for about a minute, then sounds like one of the cylinders cut out, so I turn it off.

I wait a couple minutes and try again, except this time it won't start at all.
Now, I'm not very mechanically inclined, so I try the simple stuff like checking the spark plugs and battery connection. Everything looks fine.

So, I wait another couple minutes and try again. It fires right up, but again sounds like only one of the cylinders is firing. I twist the throttle a couple times and nothing happens. Then the check engine light comes on.

I rode the bike yesterday, then cleaned it in the afternoon. It ran great. Any suggestions would be appreciated.

P.S. It is a 2012 Street Glide.

 

I suspect that your plug wires may be wet from your cleaning yesterday. Might try removing them one at a time and drying them off.

 

Maybe it's going into "parade mode"' for some reason? 1st thing I would do since the CE light came on is check for codes. Here's the instructions and code list...

Thanks SpiderPig, I'll give it a try.

 

TBW sensor maybe???

 

Check the connection right behind the A/C cover. Can't think of the name of it right now. But you will see it at about 9 o clock behind the cover. Unplug it and see if you have any moisture.

 

Do you know how to look at the DTC Codes?

when the check engine light comes on = a DTC Stored code in memory

I rode the bike yesterday, then cleaned it in the afternoon.
It ran great.
2012 Street Glide.

 

So I ran diagnostics and these are the codes that came up.....
P1511 - EFI Power Management mode
P2135 - TPS Correlation Error
P2176 - EFI Closed Position Not Learned
P0031 - Unknown

 

I also checked the plug wire and the connection behind the A/C cover and everything appears dry.

 

A 2012 should STILL be under warranty. Take it in if it'll run. Otherwise tow it. Let THEM deal with it.
