1990 Buick Reatta Base 6 Cyl 3.8L - Engine
electronic spark control module
Code # 42 comes up on my diagnostics tool referencing the electronic spark control module. Can anyone tell me where I can get one and where it's located on the engine. Also how to test to see if I need the unit. I failed the NJ emission controls due to this. Thank you for your help
