2002 Mazda Protege ES2.0 - Shakes When Stopped

Street urchins shaking it?

The EGR/PVC is most prominent during idle, I would look to these first.

Do you ever hear a "clunk" when you take off from the stop or when changing from reverse to forward gears? These cars are prone to engine mount failures, which will cause a shaking when stopped. Easy way to check, raise the hood, have someone stay to the side observing the engine, "power brake" in reverse and in drive. If the engine "jumps", you need an engine mount replaced.

engine shaking while running only with idle speed , it means

1 - low idling speed ( need to adjust)

2 - poor fuel /air ratio ( need to calibrate)

vacuum leak...

While the engine is running spray the intake manifold, injectors, etc.. with WD40 or if you have a fire extinguisher handy, spray it with starting fluid in the same areas until the idle changes. You can use water too to check for vacuum leaks.

Possibly the MAP sensor and the Street Urchin shaking the car idea.. well.. let's not ignore that one either.

While spraying that starting fluid onto a running engine, think about what will happen when the starting fluid finds a spark from that ignition system.

The best answer I can suggest is to get the trouble codes read.

It does sound like a mixture problem, but this is not the way to repair a car. Diagnose the problem, then change the needed parts. Good luck.
