After the engine warms up it just purrrs - Engine Light no longer comes on or even blinks. Could it be the O2 sensor or the EGR? :confuse:
Thanks - Paul
Ideally the temperature in of the air coming out of the vent is about 40 deg. F, but if it's hot outside, then it should be about 35-40 degress cooler than the air temp.
It's best to have a mechanic certified in a/c repairs to check the pressure and add more r-134a if necessary.
If you want to do it yourself you can buy a kit at the auto parts store near you.
If your system is blowing somewhat cool air still, don't add more than 1 small can of r-134a. The entire system only holds about 2 cans total, so if it's a little low, then less than 1 can will do.
Check your air intake hose for splits/cracks.
I just got the diagnosis engine code PO 421 (on a mazda 626 year 98).
If I understand things correctly from your discussion
- there is a 8year warrant from mazda
- the PO 421 code means that I should replace the cat converter
- doing nothing wouldnt hurt the car - just makes its impossible to pass the smog/emission check
- I could buy a cat converter for 150+ usd or so and replace it myself
thanks

Recently I was driving home and my CEL started flashing in some pattern. I pulled over and it looked like there was low oil. so I filled it up. Today the light came on again but without the flashing. It will only come on while I am doing city driving. My MPG is hanging around 10-13(if that helps at all). I was also wondering if I should spend the $85 to take it to the dealership to ONLY get the codes from OBD1.
Our 1988 Mazda 626 has been quite reliable but, recently we have ran into two problems:
1. When I try to start it, nothing, indicator lights come on but no crank. So, I am forced to push start it every time. I have to look for hills to park on, what a pain. It got this way, but at first it would fluctuate, start, not start, start, start, not start...
Then just a few days ago it just won't start without popping the clutch on a push.
What could be wrong? Distributor? Starter? I replaced selanoid already, what do you suggest?
2. Just a day ago I noticed my 626 having hard time accelerating. So when I try to get on highway it takes a slow entrance and soon I am up to speed but the engine doesn't have the same umph as usual. What could be going on here?
I also was wondering what should be checked on a tune-up? I really need to have one done soon. I want to know what is best for my vehicle.
I really appreciate any form of reply and I just can't express how impressed by all of the posters here. What a wonderful sense of cooperation.
Also this forum may have gen 1 cars on its home page
Good Luck
Is this by design or is there a fault? the car has done 102k miles, if this has anything to with it.
Any help is greatly appreciated. Thanks.
Thanks
I can use the radio and tape deck but not the CD player. Does anyone know how to reset it or remove the face and manually remove the cd?
However, my Mazda has suddenly developed another illness which is a pain in the rear. It's now 'coughing and spluttering' when I drive. I thought it may have been related to the sticky pedal, so i gave the throttle body bore and plate a good clean. Well, it fixed the pedal issue but the coughing wasn't resolved. I've narrowed it down to when i press the gas pedal quickly it struggles, there is no power and the whole car shakes. If I accelerate slowly and gently, its better. Its also terrible up a hill. I'm now desperate, huge lorries are overtaking me on the motorway! Please help!!!!! Thanks. :sick:
I think my lovely mazda has become a pensioner!......
Low pressure in the brake lines can cause the warning light to come on, which could be a result of fluid leakage.
A problem with the warning light switch for the parking brake handle/pedal could also be the cause.
If you just purchased the car then I think it would be reasonable to expect the dealer to look into this. You can't be too careful with brakes.
There is a resistor located under the passenger side dash. You'll have to unscrew two screws to get to it after you drop the kick panel. It's rectangle in shape and once you pull it out of the vent you'll see coils on the top of it.
It's about a $60 part that comes from Mazda service.
i did as you suggested and pulled out the resistor. On my model it is a black plastic housing with what looks like a silver credit card attached to it. There are no coils on it?
I live in the UK. Could this be why it is different from your suggestion?
I read in a website once when i was looking for a problem with , "Harsh Gearchanging" for my Mazda 626 93'. It said, "If your walking up the street and a mazda automatic is on your side of the road, then cross to the other side. Do not buy an automatic mazda between the years of 92' - 96'. do not except a ride in one." One month later, i pulld outfrom the curb and was cruising up the hill (slight hill) and all of a sudden, i noticed the "HOLD: light on the dash came on, the revs started to increase and the car started slowing. All my worries happened at that second. Cut a long story short, a second hand gearbox for $750 AUD. Its not exactly good either, it slides into gears with cosiderable delay, like slipping. This apparently is normal, it makes a sort of grinding noise every now and then when shifting in2 fourth. I've had enuf, its gooooooone. Rough idling ? yeah doing that too. TRied the electronic tune up, no good. tried cleaning the throttle body sensor, no good. Next step is, cut my losses , get rid of it and - Not buy a Mazda. Sorry guys ( & girls), dont mean to sound negative but i tell ya for me, Mazdas and Mitsubishi's can please them selves. Ive been building hot cars sinse i learnt to drive a manual at the tender age of 12. I've turbo'd them , nitrous oxided them, changed engines rebuilt them and made cars and bikes a small part of my learning life. I know when theres a problem, when sumthings just not rite, and Mazda have just given themselves such a bad name for these cars. Problem is, Mazda are being arrogant and ignorant to all the consumers that have payed a lot of money for one of their products that are guerenteed to fail prematurily - or how ever you spell it, lol. Happy days people. This Aussie is going to settle for the good o'l local market. A Holden car (Aussie made), North South engine with a tail shaft and diff, 5 speed "manual" trannie, minimal electronics, and just as comfy if not more so than that bloody mazda im about to say good by too, all the best folks.
I took the car back to the dealership right away. He will take it to his mechanic on Monday to find out what is going on.
I am in Ontario, do I have a right to ask for a refund? I did get a warranty for engine/tranny unlimited kms. but it won't cover anything that happens 500 kms or 15 days within purchasing the car, states it is a pre-existing condition.
What legal rights do I have? I am not sure I want the car even if its fixed now, I don't know that I will trust it in the future.
