I own a Mazda 626 LX V6 1998 and i have the following problems: for the past 4-5 years i had been getting the check engine light with the P1131 code. it is suppose to be an idicator of one of your oxygen sensors. I have replaced that Oxygen sensor in 4 occassions, and all of them twice already ever since. As i write i still get the light on. The light will go away for a few months but will return. It drives me crazy. The other problem is a noise that i guees is something lose in the back. Muffler? it makes a noise (its a metal). 2 dift. mechanics tried to solve the issues, but nothing. THey both said that it was not the suspension. third i have replaced the reservoir 3 times, and over heated 3 more times due to other leakeage. its a pain, since i don't know what is trigerring this. fans are working and thermostat is doing well. hesitation, high rpm's, bad fuel economy 12.5 city and 24 highway had been an issue from day one. used premium for all these years. not sure waht is wrong. i am sort of ready to sell this car, but if there was something to fix this one. i have seen that some people have posted to have the same problems and so on. also cars with 196000 miles on it. quite honestly, if i had that many in my car, i would not mind if my car broke on me. No disrispect, but i think that's a lot of miles on a car. but anyway, if anyone can help me, it will greatly appreciated. I only putting about 5000 miles per year lately, so if the car was to give an extra 2-3 yrs i wouldn't mind. specially as the economy goes. but if not, i wouldn't mind to pull the trigger on a accor 08 or a camry 09. power windows are the other issue, but i don't care so much about that one yet. my car is 115,600 miles.

Hello p100 and thanks once again for your fabulous efforts in informing 626 owners about the ins and outs of car care. I have had no real issues with my 626, and I am quite pleased with the car. I do not do my own maintenance, but I have a mechanic who is a family friend and whose family has been in business in my area of Montreal for fifty years - he is fantastic. My car is the 2.0 L 4-cyl. with 5-speed. Some questions: Would this motor benefit from the injector cleaner, as your 2.4 does? What about the EGR passages with the 2.0 L? I would imagine the coolant overflow bottle is the same on my car, so I'll mention it to my mechanic. I would imagine the AC compressor is the same, so I'll keep an eye on that as well. The rest of what you mention is regular maintenance. I am really easy on the clutch, and it's friction point is still very close to the floorboard. I never ride the clutch or lug the car, two practices that must be followed to extend clutch life. My car currently is at 150 K km. My main concern is with the suspension. The roads in Montreal are horrendous, this city has to be the pothole capital of the world. I would love to upgrade the suspension to handle the brutal pounding on the chassis. Right now, I need bushings for the trapezoidal links in the rear (done 30 K km ago). I have done one CV, and there is a noise from the other one. My mechanic is suggesting new shocks, but the labor cost is high. Do you know of any high quality, heavy duty, lifetime guarantee stuff out there for the suspension? I would be willing to invest in new shocks, but what kind and is there a benefit, other than improved ride quality? Can you do two shocks at a time instead of all four in one shot? Thanks

Replying to: e44 (May 24, 2008 8:00 am) The EGR passages on the 4 cylinder engine are probably different than on the 6 cylinder engine. The intake manifold has those passages as well, as it is definitely different on the V6 engine. The manifold passages appear to be the main culprit. Do not worry about these passages unless your engine check light comes on and you get the appropriate code for the "low EGR flow". The coolant overflow bottle is also different on the 6 cylinder, but is is entirely possible that it is made by the same company. Again do not worry about it unless you see a leak (coolant disappearing from the bottle). The A/C compressor may be the same and the problem I had was the bearing itself on the compressor clutch assembly pulley. I live in a very corrosive area, and park my car very close to the Atlantic ocean at work. So the car is exposed to salt spray that probably penetrated the bearing and shortened its life. The rest of the compressor looked very good when I disassembled it. As for the suspension, I think that Mazda OEM McPherson struts are quite good in quality, and relatively inexpensive. You can replace two at a time, provided it is a front or rear pair. When changing the front struts, also replace the upper mount bearings, which are plastic on these cars. They wear out and cause groaning noise when you make a sharp turn. When front and rear struts wear out, you will have decreased ride quality and most likely wheel hopping phenomenon, which often results in unpleasant vibration. So replacing the worn struts with new ones also helps keep the wheels firmly planted on the road, where they belong. As for CV joint boots, it is cheaper to replace the entire axle with good rebuilt units. It takes a while to remove each joint from the axle, and clean it out properly to reboot it. Labor being expensive, it is therefore cheaper to install a rebuilt unit. You can also find new CV axles at remarkably low prices. I found a set for $ 50/piece, and there was no core charge. Note: I am now about 750 miles away from the 200k mark with my car. Hopefully, it will make it to 200k without any incident. I recently cleaned the EGR passages. I had to remove the intake manifold and the EGR valve for this job and it was not pleasant. But it is done and hopefully good for a long time.

Today I finally hit the 200k mile mark on my car (1999 ES V6, 5 speed manual transmission). I bought the car new and I am the only one who drives it. I still get 25-26 MPG city with A/C on. Hopefully it will continue serving me well. |

Yesterday as I was driving my car (100,333 miles on it) the power died and the clutch went all the way to the floor. The clutch doesn't seem to work now. Is this an issues with the master cylinder or transmission? Any idea if I will need a new clutch and the cost?

Replying to: kew423 (May 29, 2008 7:20 am) If you needed a new clutch, the cost of replacing one at a dealer (parts plus labor is about $ 800). This does not include replacing/rebuilding the master or slave cylinders. And it does not include machining or replacing the engine flywheel if it needs it. |
