Does anyone know of any companies that will test and repair if necessary the ECM. I am also looking for how to test the ignitor coils. Are there companies that can do this also. Thanks for any input
 
As for the coils, there are ways to "test" them yourself. If one cylinder is misfiring, dial in on which cylinder, and swap it with another. Or, since you have two engines, swap all 4 coils on one engine with the coils on the other engine, and see if the problem follows the coils, or stays with the engine. Basically, diagnose by swapping coils around until you're able to figure it out by process of elimination.
