I just purchased a 2000 ES, Midnight Blue, and can't get enough of driving the car. Tons of fun. It has 59000 miles on it, so I figure it is just broken in.
My only issue is the idle speed. I bought it from a dealer and requested they fix the idle rpm as it was too low and vibrates the car. When I picked up the car, they said it was computer controlled and it was fine.
I don't trust the dealers so I just figured I would just fix it myself.
I bought a Haynes book that says the idle speed should be between 700 and 800. Mine was about 400.
I don't have much experience on fuel injected cars, but I took of the snorkel to the air intake and cleaned throttle plate with gumout and a tooth brush as the plate regularly sticks after the engine cools off.
That didn't solve the problem so before I go deeper I figured I would ask around here.
The car appears to be stock. It has new plug wires, but besides that I can't find anything that looks to have been changed from stock.
I wondered about fuel injectors, but the car drives great and is smooth on acceleration.
I know the throttle position stop screw isn't intended to set idle speed, so I don't know where to look next.
My car has a 5 speed.
I have poked around on this site and found a bunch of good information from intake modifications to ZRF5F-11 plugs, so I know you guys know your stuff.
I can see why this car has generated so much interest. Before buying this car, I drove a new Civic and a new Nissan Sentra. They were just cars. Within five seconds I knew the Mazda was what I was looking for.
Th fact that this comes from a guy in his mid forties who purchased a Suzuki RF900 this past summer and doesn't know which one is more fun to drive. That says a lot for the Protege.
Thanks for any help I can get.
