Hey all
I did a tune up on my truck today and took it out for a drive and found out at 60-70 mph it would start running really rough and shake really bad. It would only do this between 1500-1800 rpms also. Any suggestions on how to fix this?

 

Try routing the wires according to this, http://dodgeram.info/tsb/1998/18-48-98/18-48-98-v8.htm And read this https://dodgeforum.com/forum/2nd-gen...um-thread.html

 

So I routed the wires acording to the diagram and in 4th gear between 1500-1700 rpm it shakes really bad. It didn't do this before the tune up.
