1986/2.5l/Auto
While looking under the hood of my 86 searching for my no start issues, I noticed this part. Thought it was odd that it was labeled "experimental sample" and it is not carbed so Rochester through me off a bit as well.
Looks EGR-ish, but while using the handy search function on here, someone stated it was Renix only (87-90)
I guess with a build date of 11/85 everything was an experiment for the Comanche.
