You are in the Mazda 626 Forum. Your Hosts are pat & karens
I have a '97 626 ES and I recently took it into the mechanic to have the timing belt replaced. He replaced the belt and showed me where the spring had broken so he replaced that also. I had it back for 1 day and suddenly it dropped to 750 rpms, began sputtering, jerking and smoking. I stopped and when I got out I could see that the exhaust system was glowing red hot from the manifold to the rear wheels. Took it back to the mechanic who says the diagnostic says its the crank sensor. He then says crank sensor appears to be fine but a screen on the sensor has some bent and broken teeth  . He is telling me I must have run over something for the teeth to be bent and broken. I know I didn't run over anything after the timing belt was fixed yesterday...could these teeth have been bent before and suddenly became a problem or did the car skip time for some reason and damage these teeth? I don't want to pay him to fix this because he did a bad job with the timing belt....

Your "mechanic" is the most likely suspect here for the reasons I just mentioned. I cannot say with absolute certainlty if the pickup wheel is replaceable by itself, but I do not think so. Looks like you will need a new harmonic balancer assembly. Note: I replaced the timing belt on my Mazda before and the factory shop manual has a specific warning in it about using a proper harmonic balancer puller in order not to damage the crankshaft sensor wheel teeth.

I have a 1990 Mazda 626 with a 2.2l 5 sp manual trans I found my way here looking for any answers to my problem I'll explain. My car shudders/stutters when a starting out and trying to maintain a constant speed. It "shudders" in all gears while maintaining a constant speed; say 30mph . It is more noticeable in a lower gear and RPM. It completely stops above 3,000 rpm in all gears. I had it checked and it's not the clutch or transmission .I was going to check the fuel filter but am looking for more ideas.

| A general tuneup fixed the issue. Plug wires were bad. I did learn something though. I hadn't known that some Ford Probe parts were interchangeable.I thank the forum for the info. Is there a way to get a list of parts that are the same? | |

I have a 1997 Mazda 626LX which has been problem-free for a long time. About a couple months ago, the dashboard lights started to shut down every time I used the left turn signal. Now the dashboard lights will not turn on at all, and my taillights are not working either. (Interestingly the headlights and all three brakelights are working perfectly. Upon examining the wiring diagrams in the Haynes manual, I realized that they were completely separate circuits) Because of the earlier problem with the turn signal, I am guessing that the switch might be faulty. I did some research online, and many others reported similar problems with their Mazdas where their taillights and dashboard lights would stop working. Any ideas what the reason might be?
