2009 FLHX, 25K miles, stage one, **** air filter, power commander V, ran great until yesterday, (not sure if this is related, but it was raining lightly) at 50mph it just shut off, no misfire. popping or even acting like it was starving for fuel, pull over (I then said F me) hit the button and it started up, I headed down the road, it stared popping and back firing. I got to where I was going. it sat for 2 hours, started right up. 1/4 mile down the road started popping, I looked at the gages the tach was reading but the speedo was at zero and stayed there on my 30 mile trip home. wouldn't idle and stall right before I got off the freeway, its still running but very rough. I checked all the fuses all good.


thanks I could use any help and good advice

 

unplug the pcv off the ecm and take it for a ride and see if it's any better. most likely that is the problem. and if it runs ok set the pcv some where its warm so it can dry out, moisture got in it and caused it to act up or fail.

 

it has 2 lights on it only one lights up, is that normal. thanks for dry out tip Target64

 

What color is the light that's lit up?

 

with the key on one turns red and when u plug your USB cord to it and your computer that like turns green I believe that,s correct don;t have mine anymore to look at to tell u, some one else can chime in.
