Suzuki Repair: Suzuki Sidekick RPM Drop off when I come to Stops, suzuki sidekick, electric cooling fan

Question
Hay David
I have a 1995 Suzuki Sidekick 1.6 (16) Valve 2-door that I have totally tricked out with MSD SCI ignition controller, K&N Filtercharger, High-Flow Exhaust system, Electric Cooling Fan, Lowered with 2-tone paint inside and out.

The car has been a total joy but as of late the RPM's have been dropping off the almost stall when I come up on stop lights.

I replaced Plugs, Plug Wires, Distributor Cap/Cap and Cold Start Temp. Switch.

It has 76k miles on it and I noticed that this issue started around the time I loaned the car to my ex-wife and it come back with a crack in the muffler.

Any help would be great!

Answer
You'll have to check in a manual for all the trouble hooting data, but as I remember from my sidekick, the tps has lots to do with idle.  Don't think it has to do with a muffles problem, but it could concievably be connected to a marginal/old oxy sensor.  It's all in the book.  You need one.  I wouldn't even consider not having a manual for my vehicle.  Go thou and do likewise.
