96' Force 120 running rough/backfiring after new parts installed

[perna00]

The scenerio is that my engine was running perfect; smooth, power, everything. Then I lost spark in my engine. I ended up taking it to a shop and they changed out the stator, trigger, checked the cdm's and gave it back saying they couldn't figure it out. I changed the flywheel and got spark back. Now the engine will not run unless I start it and keep the idle arond 1500 rpm. If I run it lower than that; it will backfire and stop the engine instantly. When I run it at 1500; it is still rough. Maybe a wire is loose or something is not set correctly now? Any advice?

Its possible you might have a wire loose, you also need to check over all the work that the shop did ,and also look at your timing,and link/synch, there's no telling what you might find. Look it over good and post back to us what you find. MOPARMAN

Thanks for the info guys. I figured out the timing was off 3 degrees and that they mixed the cdm harnesses. 1 & 2 were switched. Runs great now!
