1996 3406E cutting out.

It could be a couple of different things causing this, timing sensor, throttle position sensor, speed sensor. You need to hook it up to a laptop and see what faults are stored in the ECM, before you start changing parts

 

Dead spot????? Thats kinda what ur discribing....sound like throttle sensor.Mine 3406e did the samething.

 

The first thing you want to do is clean the power and grounds, be sure to clean the grounds at the cylinder head stud, also check the connections at the battery's and the fuse holders.
If you have the unit on the laptop and t does not have any codes, scroll down to the keys on total and watch the totals. If when it is running and it stumbles and the tally goes up it could be the power to the ECM or the ignition switch, or it's wiring.
Just a thought!

 

Yup!! thats what mine did.its just a part that wares out over a few hundred thousand. good luck!!!

 

Did you come up with the problem I have a similar one

 

Way to revive an old thread. I had this similar issue and ended up being the harness of the injectors. The mechanic couldn’t fine the problem in the beginning, then he starting tapping on the harness connections and it sputtered. He had found the problem. Had the harness replaced, problem solved. At least for my issue on my former 3406E.
