2000 Mazda 626 blows light white smoke after reaching 50mph?

I have 2000 Mazda 626 that has been sitting for a few months.. The car runs and starts good no lights on panel on.. The battery has been disconnect since it hasn't been in use.. from time to time i start it and move it.. all fluids are full no leaks. Belts have been changed fluids as well. I have noticed once the car reaches 50mph the car will begin to blow light white smoke from tail pipe.. It stops blowing smoke when the car is idling. No other problems so far. I was told it could be Throttle Body need to cleaned.. but when I think of smoke coming out it leads to head gasket... Mechanic said it needed to be reprogrammed.. Unsure what that has to do with the smoke.. Any help will do

Basically it needs tuning and / or cleaning, you can a try an Internal Engine Cleaner Crc Motor Treatment 16 6.55 eBay. and see if that helps, i understand your worries about the headgasket of water problems, the best way to tell is to take your oil cover off the engine and look for a white substance (mayonaise) if its black or brown its just oil and all is good, but if it is creamy white or going that way then oil has mixed with water and you may have a problem, but with it been white smoke (not to mistaken with steam) then it's prob just a tuning issue.

SOURCE: My 95 Honda Civic dx (revving up and down)

sounds like you might of blown a head or intake manifold gasket or cracked head. If it sounds like a rollercoaster going up the tracks or tractor sound. it's that. It's expensive repair. My advice if you dont know anyone cheap get another used car until you fix it or whatever your situation is. Also, it idles up and down because of the air escaping from the crack. If engine doesnt hold constant pressurethats whate happens. everything is to the T when working with vehicles. Plus redline dont matter, theres a cut off point, however because of the high rev you could of caused the over rev and blew a gasket or cracked the heads. Especially if you didnt have the proper fluids to keep the temperature down. Good Luck. Been there.

I have a 2000 mazda 626 and my air conditioning is not getting cold. The freon is full in the car.the car smokes at a red light when just sitting there while air is on. Wht could be the problem?


Is it possible that the clutch on the compressor is not engaging or the compressor itself is locked up. When you turn on the air, does the engine bog down noticeably? If so one of the two above are likely.

My mazda 626 has a strong potent smell coming from the exhaust


You don't mention what that smell is reminiscent of?

You don't mention the colour of the "smoke" and you didn't say whether the engine is petrol or diesel?

You don't mention whether the road behaviour/performance is normal?

White smoke is almost always steam or in the case of a diesel it could be an unburned fuel mist, grey/black is excess fuel and blue or grey/blue is burning oil.

Some steam is fairly normal until the engine and exhaust system is hot but excessive amounts could be one symptom of head gasket trouble. If the engine is drinking coolant and sending it through the exhaust as steam it will sometimes smell spicy.

Burning oil smells a bit like burned eggs in the frying pan.

If the car hasn't ultra-low sulphur oil and fuel the catalytic converter will convert sulphur traces into hydrogen sulphide - the bad egg gas...

If blue smoke started but then it stopped what does that mean?


When you stop at the traffic lights and then drive off and you get blue white smoke then you have either worn piston rings or worn valve guides where oil is getting into the combustion chamber.

2000 mazada 626 on sometimes will not start. starter engages, spark to plugs, and I can hear the fuel pump running. after it sits for a while it will start and run for a week before it happens again. I...


Check fuel pressure
The fuel pump may be worn out &
binding up every few days & stopping
the fuel to the engine.
Then you have other items that a repair shop
can check, that may be causing your problems.

While starting car little smock come for few mnt why ?


If you get a little puff of white/blue smoke just at start up , it probably means that one or more of your valve guide seals are worn.
While engine not running , a bit of oil gets in the cylinder , when it starts the oil burns off causing smoke. If it was smoking all the time , I would say rings are worn. If it is black smoke at start up , it indicates a fuel mixture problem. The valve guide seal problem may get worse over time.
On your post you say " for few mnt " if that means a few moments , than Valve guide seals , if you mean a few minutes , than more serious piston ring problem. Change your oil , and add a can of RESTORE , it will fill small scratches in cylinder walls , but will not fix badly worn rings.

Engine shudders and dies trying to go from a red light


The engine has an electronic module where the spark plug wires connect to. Replace this and you will see the difference. Once this module heats up it will malfunction. After cooling down the car will start up again. hope this helps.
