01 dodge cummins tach not working
Hey guys havin some problems with a truck I bought not running. Troubleshot it found out it needed a ECM found a used ECM out of same year of truck same transmission. Didn't get ECM reflashed. Sometimes tach won't work and engine feels sluggish. Then I'll be driving and tach will work and engine has tons of power. Also will **** off on me sometimes when I'm driving it down the road. Any help is appreciated Codes are p0341 and p1689

well that worked. Only took it for a 10 km drive but it would of shut off before I made it out of town before and tach never shut off once. And no more engine light so far knock on wood
