I just bought a 1997 mazda 626 the ideling at a stopped position doesn't bother me enough to give up on the car if anyone might know the first place to start I would be deeply thankful
Also i have read that the 626's have power problems (I have had the experience the windows don't do good if you try to use them all at once and the car doesn't even turn over when the lights are on but that has only happened twice) i'm thinking about putting a new stereo system in it and i didn't know if that was a bad idea reading about the problems people are having
#2413 of 2547 99 V6 Engine Noise

This is an unusual noise. It is coming from the front, passenger side, and is only heard when the a/c is on. Sounds almost like a "slapping" type of sound. I suspect belt or pulley related maybe?? There is no other belt type of sound though, such as a screech. Very strange. And, I do not know if related, but when the a/c is on, as the compressor cycles on, the headlights/dash lights will briefly dim. Any ideas on this unusual sound?

I belive that the compressor is to blame. the sound you describe along with the time it is apparent are a dead give away, but this is only verifiable by using a mechanic stethescope to probe around the compressor and listen for when the noise is most noticable. and don't just touch the probe to the compressor body and be satisfied, touch it to the front cover of the motor, to the alternator, to the power steering, and so on. By doing this, you'll find the culprit in a hurry. as for the guages and lights dimming, I belive the alternator is being dragged down by whatever is causing the slapping noise. I'd almost bet that when you test spots with the stethescope, you'll find the noise at the compressor, which indicates it's very low on oil, or a mechanical failure. thus, causing the engine to work harder just to turn the AC compressor. a stethescope is about $20 at any parts store.

I'd move on this noise right away. If the AC compressor seizes, you have contaminated your entire AC system and then you have a big mess and a BIG expense.

Thanks for responses. After listening closer, the noise seems to be an upper engine noise. Decided to check oil level. Was down about 1/2 quart. Topped off oil, and no more noise at any time now, with or without a/c on, at idle or full throttle. Plus, a/c has never given any indication of an issue with it, still blows nice and cold as it should. I will tell my daughter to listen closely for any sounds from the engine. I probably should add that the car had been sitting for about 5 days without being started when I started it up and heard this "noise".
Also, I had posted an earlier thread about an idle surge issue. After running some Lucas in the last tank of gas and pulling the negative battery cable to reset computer, no more idle surge.
Car needs to "survive" one more year of college, and then it is not my problem Car has 124k on it now.

Well, if your power steering is leaking, and it's not a small leak that you can just keep filling up before it runs out. Then, I would suggest that you do not drive it at all. The leak came from a bump you stated, maybe a power steering hose got busted, or loose. It could also be the rack and pinion unit got damaged from a big bump too. If you have to keep useing the car, and you can't afford to fix it, then you might be able to remove the power steering belt(only if it's a seperate belt and doesn't power other important parts to) so that the pump won't be running dry, but I'm not sure if that's safe or not, so you might want to get advice from someone else about that.

Just started having problems . Put the car in Drive from a standing stop when I hit the gas, the engine revs but is very slow to take off,almost like its in neutral. It does take off, a bit sluggish . At higher speeds, it seems fine. Can anyone help.

I have 2000 626 and this just started on my car. This what I have been told to check, first is to change out the spark plugs. then also change/flush tramsmission fluid and last to make sire that your belt is tightly secured and not loose. The last thing to check is the pully's. Hope this helps

I have a 1997 Mazda 626 LX 2.0. Can't get it to pass the emission test. Code PO421 comes up and don't know what it means? Had Code PO133 on the test , but it's not coming up anymore after changing both o2 sensors,spark plugs,new spark plugs wiring. Can you tell me what Code PO421 is?
