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.

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?

Grinding noise in front end


Hi
Had the exact same problem, on a used 2003 Protege ES with 82,000 miles that I purchased.
Started with the loud "road noise" I thought well maybe thats just the sound that it makes.
And then noticed that it varies when turning.
This will continue to get worse and then your abs light will come on when it gets bad enough to trigger the sensor..
It turned out to be a bad wheel bearing.
Take it to a shop and have an experienced mechanic check it out. Its repairable.

Fog Light


have you checked to make sure it's not just the bulb ? if it is there are likely two screws holding the lens on .... or you have to lay on your back and reach behind the light and see if you can remove the bulb that way....
