#2238 of 2547 Engine Shuddering
Dec 27, 2006 (4:17 pm)
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.

When was the last time the plug wires were replaced? Plugs? who replaced the spark plugs? It is possible that the porcelain insulators on the plugs are cracked, causing a miss.

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 knew it! Thank you for verifying that for me. We had to wait a week but we got the part (finally). The mechanic did it for free (what?!). I am so glad to know what actually happened.
#2244 of 2547 Taillight and dashboard light problem on a '97 626..
Dec 31, 2006 (6:25 pm)
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?

I recently had the same problems with my 95 626. You most likely need to replace the combination switch. This requires pulling the sterring wheel to access the switch. Recommend you find a combination switch from a reputable salvage part dealer since a new combination switch from the dealer will likely be well over $300. My switch cost about $100 and came with a 3 month warranty. You can find sources on the internet. Mine came from a mazda parts dealer in Atlanta..mazdamart..that specializes in mazda parts. Good luck.
#2246 of 2547 First gear synchro noise
Jan 01, 2007 (11:20 am)
My 4 - cyl. 5 - speed 2002 626 with 110000 km sometimes makes a grinding noise when downshifting into first gear at low speed. I cannot figure out what causes this. The noise is like trying to put a car into gear without engaging the clutch - the sound of the gears not meshing together. Suggestions?

I had the same clunking noise coming from the trunk area on my 2000 626. I read on another forum it is the sway bar bushings that could cause that. I changed them out and it fixed the problem.
