SOURCE: No spark?
Hi, common thing with the mazda was the coil or the ignition amplifier going faulty, both of which are located within the distributor, the coil ususally gives the symptoms you describe, a weak spark. The coil is the most common failure aswell for your vehicle i would recommend a new one, also make sure distributor is spinning as it could just be a case of a broken timing belt.
Good luck Davelee

This can be your Idle control valve, when you turn the air on it puts the engine under load and your computer will increase the idle automatically to prevent the engine from cutting out.
When you are standing still and the car is shaking, by touching the accelerator very softly does the shaking stop? If so check the idle control valve.
I hope this will help.

before you spend any more money on your vehicle run a cylinder compression test. I know it seems unlikley with less than 100,000 miles but 119 engines do like to burn valves. the LH fuel injection system was only used from 93-95. LH is a germen abreviation for hot wire mass airflow. The later systems use a hot film. Your vehicle has electronic fuel injection so why did you have the fuel injecters pressure cleaned. unless you have the cis system which means your car is not a 95. Motor mounts are also a very common failure on that vehicle. In any event rule out the worst case and perform a compression test because it really sucks to spend alot on an engine and find out it needs a valve job. I'm assuming that the check engine light is not on. although wireharness issues are another common issue. these early C.A.N. cars are very difficult to troubleshoot electronically and the information provided by the factory is difficult to follow.

Perform a valve clearance inspection and adjust if necessary. Tight or sticking valves will cause a misfire or rough running concern. Note: Perform valve adjustment when the engine is stone cold. 4cyl: INT 0.26mm EXH: 0.30mm (V6 engine are hydraulic and no adjust necessary.) Also check for a sticking or stuck open EGR valve. For diagnostic purposes only: Remove the EGR valve. Place a business card over the EGR passage and bolt the EGR valve back on. This plugs the EGR ports and if the misfire goes away the EGR valve is partially stuck open and is defective.
Check for low fuel pressure. Check for low compression. Check cam timing. Check for a weak ignition coil. Also don't over look the possibility of worn or broken engine mounts which cause excessive engine movement and engine vibration. -hope this helps
