#838 of 2544 Check Engine Light---AGAIN
by mark38l
Dec 29, 2001 (7:58 pm)
The Check Engine Light has come on several times on my 1998 Mazda 626 LX starting at about 40,000 miles it will stay on between ~500-3000 miles (about 1 to 5 weeks) and go out only to relite 8,000 to 12,000 miles later. The car now has 74,800 and has relite.
I have experienced no problems with fuel economy, pick-up etc.
Is the light timed to go on and off at regular mileage intervals?
I find the light worthless and a damm annoyance.
Thanks
Mark
#839 of 2544 Transmission Service?

Don't extend transmission service if it's an automatic. My Mazda mechanic who won many national awards in Mazda competitions said change it religiously every 15,000 Miles. They also put in anti-wear additive like Wearguard or Lubegard. He has over 20 years experience on Mazda engines almost exclusively.

Oxygen sensor may need replacing. The *&^%$#
!#$#$ thing is unfortunately probably a dealer item. The maintenance manual says that they need to be changed every 50,000 miles. Also, if it has an MAF sensor then it could likely need to be cleaned. Did you replace the spark plugs and do a tuneup at 60,000 as recommended?

My '99 626 (4cyl) 55k miles which has been perfect has started to miss when cruising
50 mph and then accelerating. Have just started noticing some hesitation for the first time. Plugs were changed at 30k and will be changed again
60k. Its been very cold (10 degrees) and I wonder if it could be water in the fuel making the engine miss. Any ideas?

check the fuel filter, and try some dry gas.
My 98 626 has 73k with no real problems (knock on wood)
Good luck
#843 of 2544 Where is the fuel filter?

My understanding is that the Mazda 626 (99 4cyl) fuel filter is in the tank and that you don't change it. Anybody know for sure?

Unless they moved it just for '99, it's under the hood. In fact, in the 2.0-liter, it's usually under the cruise-control actuator, a smidgen northeast of the air cleaner. Not especially easy to get to.
Make sure you kill the fuel pressure (yank the relay out of the box while the engine is running) before you mess with this thing.

I have an 1988 626 5-Speed. It has given me no problems for the past 5 yr s. Then the other day we warmed it up for about 15 minutes, shut it off and it wouldn't start. When you turned it over it just went click, click, click and then nothing. Battery is 2 months old, went and got a new one, no start. Hammered at the starter and it started for 1 minute, then nothing. Replaced starter today. Now I have only top gears, 1/3/5. You can hold it in the lower gears, but if you let go it grinds. Thought maybe my clutch had gone but I still have smooth shifting in the top gears...Checked the linkage on the hoist and it looks fine??? Any Ideas? Of course, dealers say transmission, and of course, I am skeptical. Would there by any warning that your transmission was failing? Everything else, knock on wood, is excellent. Thanks in advance for any input!

I've got a chance to buy a 2000 EX V6/automatic with 16k miles. What are the problems (if any) with the V6 powertrain in the 626? I'm assuming that they are a little more reliable than the 4 cyl models. Any feedback would be appreciated. BTW, the car I'm looking at has abs/traction control/Bose system w/ cd changer for $14k. Sounds like a pretty good deal to me.

jonbgood. that sounds like a good deal to me. Nice car. Real nice car.
legacy - well, that sounds strange to me. Just based on the grinding/holding in gears/missing low gears I would also say its the tranny. BUT, it is odd that you had the starter problem at the same time. Its either a bad coincidence or the 2 problems are related (which is possible). Just bad luck, I think.
