Mazda runs bad - MX-3 Mazda Cars & Trucks

Either the camshaft lobe is worn badly or the hydraulic lifter has collapsed.

You might check the coil. If there's no spark it has gone bad (around $100.00 at Auto parts stores, if you replace it yourself.) That's the easier one to fix. The other is the distributor. They also go bad, and cause the same problem.

you could have a bad oil pressure switch leaking oil,oil pan gasket,rotted out oil pan,head gasket leaking oil and running down the block.

you could have either a bad alternator that isnt sufficiently charging the battery or a bad ground somewhere that is causing the battery to run constant power until it dies

he may need to replace the ignition coil... when its hot it gets faulty its more likely to give a bad run then you have to wait for it to get cold to have a good run

I have a 2000 Mazda MPV where the same thing just happened. Unfortunately it came back for a second, and my wife pushed one down. I took it to a glass shop, and found that the driver side power window switch was bad. It runs about $178.00 at the dealership. It takes about 2-3 days to order. Unfortunately not even the import places carry it. I did find a few used on Ebay for about $50-$70.

First, check the relay for the cooling fans. Not sure about Mazdas but Fords have two coolant temperature sensors. One for the gauge or light on the dash and one for the fan relay. Check and make sure the sensor hasn't went bad or come unplugged. If these don't fix it the fan itself may be bad.

starter wont turn engine over? if so bad battery or bad battery connections,check alternator out put when u get it running if it is the battery cause it could have started there

yes the sensor and it will not go away on Mazda Millenia even though you replace that code it will show another one Mazda Millenia Sucks & Mazda Parts are Expensive too

sounds like air flow meter but best to put in garage on computer
