1996 Mazda MX6 6 cyl Front Wheel Drive Automatic 174000 miles

Hi There. My Mazda MX6 just started shuddering / shaking when accelerating from 1st gear. The RPMs drop and the more I push the accelerator, the more it shudders and the slower it goes. I can have the gas pushed all the way to the floor and the car wont go over 40 km/h. When ideling, the exhausts sounds like its blowing bubbles (put-puting).

Lack of acceleration, chugging, hesitating, bogging etc. Could be caused by one of the following below: Possibilities: Inspect and test all the following listed below: Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note: If it doesn't apply disregard it.
