Big engine problem with 2.0 V6 from 1995.

When going through heavy trafic and the engine is warm enough for the fans to start the rev counter drops to around 450 RPM which causes the engine to finally stall...

Whats up with this? Distributor maybe? ignition leads? The car runs fine when cold and warming up untill it gets up to around half way on the temp gauge.

Please Help. I have heard mazda had many distributors failing in this year.

Could be your battery is on its way out .....

any way to check this? or just buy a new one?

It could be your alternator

You can get your battery tested at a battery and exhausts place I guess. To check your alternator, measure the voltage across the battery while the engine is running, it should be in the region of about 13-14V I think.

Yeah - if you take it to a decent battery place, they can test it and let you know whether it's the battery or the alternator or what-ever ...

Whats the normal tick over for your car? If less than 750 to 800 then it may just need the idel speed adjusting.

i warmed up the engine and set the idle at 100o RPM to see if it helped as it was running around 800 before.

It didnt help much though but have been told its probaly the alternator on its way out as it also happens sometimes when i put the AC on

So if anyone has a spare cheap alternator lying around feel free to contact me

Not too sure it'll be the alternator. That just charges the battery so the engine has a spark to run. If you turn on more appliances thn it'll kick out more juice. If it's on the way out and not charging the battery light will start to glow, dim at first then brightly.

Have you checked the following, Fuel filter not blocked, plugs gapped corectly, rotor cap and arm clean and undamaged, no water in the petrol, and a guaranteed killer of engines, splits in air / vaccume hose's or the manifolds.

Thank you very much for all the posts i will check it out..
Cheers

Well i bought a new battery for it the other day but without luck. Shit
