When the weather cools down in the fall and spring engine idle wants to hunt or surge.
I had the same problem with my previous 1989 Suzuki Sidekick and two 1991 Metro's.
I have been unable to figure out what the issue is, but assume it is unique to Suzuki vehicles.
I love the vehicle in all other respects. I call it my poor mans jeep.
I enjoy leaving the top off all summer and four wheeling in the farm fields.
I would buy another one if they still made them.
My tracker had the same "uneven idle" when cold. I took off the e.r.g. valve (bolted onto the manifold underneath the throttle body-held on with 2 bolts) I cleaned it out with solvent and re-installed. problem solved for free!!!
