Car Information:
Saab/9000ce
Year: 1996
Engine Size: 4 cyl turbo
Trans: Automatic

Issue / Question:
My check engine light is on saying “#4 not firing”. Is there away to make sure it is the coil pack or could a injector do the same thing? I pulled the pack and placed spark plugs in it and they all look like they are firing. This is a pricey part and with the wonderful gas we have to use now I would like to make sure its not an injector or something else.

Answer:
We use noid lights on both the injector harness and coil to the plug. We can also look at the data stream and if not available we brake out our lab scope.
