ok so i have the same car you do but it is a 99. I just replaced the thermostat about 3 months ago because my car started to run hot when i would be stopped at a light or in traffic, but as soon as i would start to drive it would go back to half or under half near the cool side. It is doing it again so now I am wondering if it is a sensor. I had a coolant flush and fill when I replaced the thermostat, it has 131k on it. I don't know what to do with it, but this is a problem I have been having as well. I am not leaking anything and the fans are working.

I just have had to recently start fixing things in it, overall has been a great car up until the past yr. My EGR valve was stuck open so I bought a new part and had it replaced from my mechanic a little over a year ago. The engine light was on not long after the replacement giving me the same code 400. It was a flow problem. How do I fix this? Also, I just had my thermostat replaced and a flush and fill because my car started to run hot while I was stopped. It just started doing it again, although it isnt everytime I am driving it is so random. Once I start driving again the gage stays at half or towards the cool side. Could this be an oxygen sensor or something with the AC?

Pulled connector for air flow sensor. Car ran the same, definitely no better. I have also noticed that if I give it gas will idling, instead of the idle settling back down to its higher than normal level, it surges back down, varying between 1000 and 2000 rpm until it settles in the 1000-1200 range. And, again, if I turn the a/c off, it seems to idle as it should, in the 750 range. Check Engine Light is not on at any time. Very strange issue. Any other suggestions are appreciated?? Also, I doubt it is related at all, but I also noticed that the temp guage has a slight flutter to it. It does not hold dead on the indicated temp., but looks like it has a nervous condition. Not flucuating, just not holding steady loke all of my other cars do.
#2409 of 2544 Engine makes hood vibrate
Aug 02, 2008 (11:45 am)
I have a 2001 Mazda LX 4D Sedan,4-Cyl, 2.0 Liter, automatic transmission. It has 43,300 miles. The hood vibrates like crazy and my car sounds like an airplane. Does the drive or timing belt(s) need to be replaced? I haven't had much maintenance done on the car besides changing the oil.

Follow-up. Check Engine Light actually came on last night while daughter was driving, and again today. Took it to friendly auto parts place and had code read. It read Code 1131. They printed out a list of potential issues, anything from o2 sensors (night likely), to Mass Airflow Sensor (also not very likely), to a fuel injector issue. Whatever it is, it deals with bank 1. Anyone else have this code come up and figure out how to resolve?

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 2544 99 V6 Engine Noise
Aug 14, 2008 (7:09 pm)
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.
