I have not made one yet, but grounding kits have been around for along time. The Intrigue is the first Aluminum block engine auto (and non V8) I have ever owned. Once you make the switch to Aluminum it is something I would seriously consider. Check around the Import scene for more information. The guys diagrams are pretty good. Any ground that goes through the engine or does not directly ground through the chassis I would add another ground to the chassis or to a custom ground strip. Once I have my service books and read up alittle I will make my own (1-3 months). It may be smart to go through every main electrical connection and clean off corrosion and coat with electrical (diaelectric) grease also if you are having problems.
