#1450 of 2547 Idle Air Control Valve & Gasket issue...
Mar 22, 2003 (8:13 am)
I posted message # 1395 to this board back in January and the outcome to that inquiry was that the dealer I purchased the car from replaced the PCM at no charge because my 2000 626 V6 was still just under the warranty period at 49,500 miles.
The dealer stated that they could not get any error codes or get the car to start so they just replaced the PCM to get it running again. The first week of March, the car stalled again on the highway. This time I was able to start it (after several tries) and made it to work. I went out after work to start the car and it would not start. The next morning I had the car towed to the dealer again. At the dealership they were able to start the car and they kept it for 4 days.
The mechanic at that time told me that he could not re-create my problem and without any error codes, had no idea what was wrong with my car. Comforting thought huh ? Anyhow, I picked my car up again and this past week, the check engine light came on and the car started to run rough and felt like it was trying to stall out again.
Back to the dealer for a THIRD time for the same problem ! This time I was told that I needed the
Idle Air Control Valve & Gasket replaced...to the tune of $ 650 !!! You see, now my vehicle has 54,000 miles and is out of warranty. I argued that the problem first occurred while the car was still under warranty. Mazda has finally agreed to pick up the tab for the part, BUT the dealer wants to charge me $ 160 for the labor. They are also telling me that I won't get my car back for a week because they need to wait for the part and that a loaner car is not available. Is this how any of you other Mazda owners are treated by your dealership ??? A friend of mine told me that this should be covered under an emissions warranty - that this warranty runs for a longer period of time & miles...does anyone have any specifics on the emissions warranty for this model ? Is this a common problem on these vehicles ? Thanks everyone for your help !
#1451 of 2547 626 warranty period
Mar 22, 2003 (8:56 am)
I don't believe anything is covered beyond the 50,000 mark except the catalytic converter (80,000). I had a similar problem to yours. Mazda did the warranty work even though I was over the 50,000 mark because the problem started within the warranty period, and was documented by the dealer. They also gave me a rental car and did not charge me any labor. A favorite trick of mine (and I do it quite often), is to get REAL LOUD when you are at the dealer. Make sure lots of people are around. I often get my way in order for them to get me out of the place (and not take any other patrons away from them). As I have done, just remember these times once your warranty/extended warranty expires. You need to be thinking of what your next car will be, because there are still lots of bills ahead of you my friend as long as you own this Mazda. I still have my '96 626, but will donate it away before it has a chance to leach real cash out of my wallet. I suggest you do the same.

I am curious though...was it Mazda or your dealer that picked up the labor cost & the rental car ???
How many miles on your 96 now ? Have you had any other problems with your Mazda ?
Mar 22, 2003 (3:55 pm)
Hi Jim. I don't believe the dealer EVER picks up the cost. They pass it on to Mazda. That certainly was the case with my O2 sensor problems. In fact, it amazes me how quickly these dealers will screw their parent company out of money. I can honestly say that there were repairs done to my car which probably were not necessary. As for problems with my '96 (87,000) miles, I would probably take up 2 pages with problems. Let's just say, I put $3,500 of repairs on my $650 extended warranty. Some of the highlights included: strut top bushings, 2 radiators, rack and pinion steering, master cylinder, 2 additional transmissions, water pump, timing belt...About the only thing I have paid out of pocket for was I decided to put on 4 new struts. Although they were leaking, I decided to not file a claim since I was right at the end of my extended warranty and I figured since I had not had a total breakdown, they would not go for that one. Currently, my check engine light is coming on since the catalytic converter is beginning to fail. I won't replace it until it does. Also, my engine mounts are beginning to weaken. Again, if you have a paper trail showing that your problem started before your warranty ended, I would either do the screaming thing, or call Mazda directly. Trust me, your dealer won't want you to do the latter; so make some noise either way.
#1454 of 2547 '99 626 LX 4 Cylinder Auto Hesitating
Mar 23, 2003 (6:55 pm)
Hello all. This is my first post in this particular forum, and it's for a friend with a '99 626 LX 4 cylinder automatic. The car currently has around 75,000 miles.
The main symptom is severe engine stumbling and hesitation at idle and when accellerating. The check engine light comes on occassionally, and the codes indicate too rich a fuel mixture.
The car was taken to the dealer three times, and each time the mechanics replaced the spark plugs and the spark plug wires. The #1 plug was consistently carbon fouled every 6 months. New wires and plugs would help for a short while.
The problem has gotten much worse. The plugs foul within weeks, and all the chambers are effected. The new plugs only lessen the hesitation now.
Over the weekend I checked the color of the spark on the plugs, and noticed it was orange rather than blue. I swapped out the coil with a new one, but it didn't help.
Any ideas on what is happening?
#1455 of 2547 1991 626 electric fan troubles
Mar 24, 2003 (7:39 am)
My '91 626 overheats after a while. The electric fan is not coming on. Is there an easy way for me to check if it's the fan motor or the sensor? I'm running this on a low budget. Thanks.
#1456 of 2547 TYGUY & emissions warranty

The carbon buildup on the plug/wire is the most common cause of hesitation on the 99 and up 626 four cylinder. It is important to replace the plug and wire of the affected cylinder that is misfiring. From what you wrote, this was done on multiple occasions. A bit of information would help more...what was the code/codes that were retrieved from the cars pcm? Also find out if the timing belt has been replaced and that it was installed properly. There is a recall for 97-98 626 timing belt tensioners being faulty and as a result cause slack in, and eventually failure of, the timing belt. This can cause hesitation and poor running. The recall was limited on paper to certain 97-98 626's, however, mazda failed to recognize all the cars that it applied to (mostly 98s) and as a result there are cars being brought in all the time with no open recalls yet have the faulty tensioner from the factory. It wouldnt surprise me to find some 99's that might have the same problem.
As for whats covered above and beyond the 3yr 50k warranty, the catalytic converter and the PCM are all covered up to 8yrs or 80k miles.
#1457 of 2547 Hesitating '99 626 4 Cyl
Mar 25, 2003 (7:12 am)
Thanks for the advice, rotarykid. Unfortunately, my friend didn't record the code numbers when the dealer pulled them. I'll have to wait to learn those until the next time he takes it in. I'll be sure to warn him about the belt tensioner issue.
I think I may have found the root cause of the problem, though. I searched some of the Technical Service Bulletins (TSB) yesterday and ran across SB614906, which can be found at http://www.nhtsa.dot.gov/TSBScans/sb614906.pdf
The TSB states that rough idle and hesitation during acceleration on '98 to '01 626s can be attributed to a leaking intake manifold gasket. The symptoms identified in the TSB match what is happening with this particular 626, and the VIN number falls under the ones covered by the TSB. Since this TSB was issued on 10/18/00, and two separate dealerships identified and documented the problem but failed to fix it properly while under warranty, my friend is going to insist the TSB be performed without cost. I think he has a good case.

and the leaking intake gasket is very easy to determine. I would be surprised if ANY mechanic missed that. The code P0171 goes along with the problem.
#1459 of 2547 626 Paint Problem
Apr 02, 2003 (6:57 am)
I have a 1995 Mazda 626 ES with green paint. I know that the car isn't a spring chicken but I've had problems with the paint for the past couple of years now (and certainly there are MANY older cars out there with original paint in good condition). It started to get little hairline cracks in the paint - I took it to the dealer - he said sorry it's out of warranty. Over the past couple of years the hairline cracks have gotten worse and now the paint has oxidized (I think that's the right word). I called Mazda - they said it's up to the dealer. I'm wondering if anyone else out there has the same problem and if you've been able to successfully get Mazda to do anything about it. Just in the area where I live I've seen a half dozen other 626 Green cars that appear to have similar paint issues.
