Check the spark plug for Cylinder #3. Check the boot and wire around that plug and back to the distributor/coil. Likely have water (from washing your engine) arcing and shorting that cylinder & causing misfire. Wait for a long time for everything to dry, should clear itself. Also, hope you used MAF sensor cleaner to clean the MAF sensor. If you used something else, you might have ruined the sensor - it is very delicate.

Po303 is a #3 cylinder misfire, you may have got it wet. and it is either the plug or wire. it may be a vacuum leak or just about anything, check the wire and plug first. if that does not work. check hoses etc. good-day!

    if the car has coil on plug try switching it with another cylinder and resetting the light drive it.if the light comes Back on check the code again.if it's the same try the same thing with the spark plug, it the problem moves to the other cylinder then that part is bad.it's an easy way to check parts without just going out buying new ones.

SOURCE: 2003 Mazda Protege car is shaking When Drive and Engine light stay On

I bet it also feels like it wants to stall as well. I think my car was at around 65k and it did the same. It is the spark plugs and the coil. My mistake was going to the dealership where they charge you too much. Any experienced mechanic can do it. Changing the coil is also in the manual.

SOURCE: 2001 Toyota corolla hesitates on acceleration

Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust).

SOURCE: 2002 Mazda Protege acceleration problem

I had the same problem and found that the air admission tube was badly cracked.

Since this let air enter the engine downstream of the mass airflow sensor it is not measured so the engine ECU don't send the proper amount of fuel to provide the right air/fuel mixture. At higher RPM, the vacuum in the tube is enough to close the crack and hide the problem.

I temporarly repaired it with duct tape until I get the part.

SOURCE: For 2003 Mazda Protege ES model 2.0L 4cyl engine;

Check the air inlet boot going from the air filter to the intake for rips or holes. If rips exist, this would allow air to bypass the filter and mass air flow sensor and will lead to a check engine light appearing. The code would read "too lean, bank 1." If this problem is allowed to continue for long periods of time, the EGR ports will have to be cleaned out and maybe even the intake.

SOURCE: code po705 mazda protege lx shaking rough start

The Code you refer to is P0705 Transmission Range Sensor Circuit malfunction (PRNDL Input). It is a possiblility that because this code is present, this sensor is malfunctioning. If it is malfunctioning, that means the engine needs to "guess" the value that this sensor is responsible for. In most cases when this happens, the engine will go for a value that ensures the car runs. The engine will not try to run smooth or efficently, it will only try to run. It is my guess that if you have the sensor checked and replaced, the problem might be fixed. Please let me know if this answers your question and please rate my response. Thank you

My mazda protege 2002 started shaking after I put in a new stereo system I thought it might be my battery terminals not hooked up to the battery properly but it wasn't Any suggestions


Firstly remove the stereo system and see if that fixes the problem as if it started after you installed it then you have interfered with the power systems for the ECM. Best have the stereo system fitted professionally if that is the case.

I have a mazda protege 2003 and my car stinks like rotten eggs when i put on the gas and on top of that, my engine light is blinking and my car shakes when i stop at a red light!


i have a 2003 mazda protege. this is the third time my check engine light has come on. the first time the car started to shake when i stopped at a light and the check engine light came on. i had a readout done and it said misfire. i took it to a garage and they changed my spark plugs and wires. 2 weeks later it came on again and my car started to shake whenever i stopped. readout said misfire. they fixed the coils. it has been 2 weeks since then and my car started shaking again whenever i stop and the light came on. what could possibly be wrong with it?

Mazda protege with no dashlight on.


First you must cut the Dimmer wire from your stereo installation.Second, replace the 5amp or maybe the 7amp fuse that blew at the fuse panel near the LEFT foot rest.If you are certain that all the fuses check fine, then go to your MAZDA dealer and purchase a new thumbwheel dimmer control,because the rheostat has burned in your present one.Do not reconnect the dimmer control wire 2 your stereo wiring,because U don't need to.
