60 series Detroit acting up..need help ASAP

Does it only feel like it is running out of fuel for a split second, then come back alive? Almost as if it is missing a beat?

 

When it acts like it is running out of fuel does black smoke coming shooting out the stack. Had this happen to me last year with my Century and it was the EGR valve.

 

2000 FL very unlikely it has EGR ...

 

by rother has a 2000 classic that did just the same as yours turned out the ecm fuse holder in the battery box had that green crap in it he cut the holder out truck ran great got him off the road he did put a new fuse holder in when he got home

 

It may be water in the fuel , ask him if he just purchased fuel . This happens often in NJ and low lying areas after it rain if the service station doesn't take care of seals near the filling area. Id say take down the filters and pour the fuel into a cup to see if it has water in it .

 

Mine did that when SRS/TRS sensors were going bad. Was told it is a common problem on old Detroit engines. Had mine replaced, never experienced the problem again. However - if not diagnosed and this IS the problem, if the sensor goes totally bad or if the wiring disconnects, it will cut all engine power. These sensors tell the ECM about the timing information and when to fire fuel in. They are not expensive, and I was told some people keep spare sensors with them at all times. Let us know how this turns out.
