I still have a few connections to investigate with my '93 LWB intermittent mis-fire problem, but is there any history of the Lucas kit STC1856 IAM module going bad?
I recall buyng the kit from a non-AB source, truck wouldn't run right, finally took it to the shop, and they said the module I had was bad, and they installed a new one, problem solved. Now that it's doing it again, I wonder if that is again the problem.
How can I test the unit?
