well the last two days my exhaust was sounding marbles in the can sort of , sounded really distorted when bringing up to high rpms.. I felt i had no power at all even with half way or flooring.So i thought maybe it was the heat. Anyway all unsudden im pulling into sonic and the car dies and wont crank..

Waited until some of my friends to arrive to help me out.. We rolled it back and then it started, but had unsual sounds and a real hard idle. Its running better now.

You guys have said this is has happened before and then down the line a new engine was needed. about 2 weeks ago i had it serviced at mazda and they gave me the new flash update. Could this possibly be it or im outta my mind and dont want to admit my engine is going out?

 

how often do you redline?

 

once a day maybe 2

 

Check your CAT first.

 

check to see if something came loose or went bad?

 

both

could be bad coil, bad plugs, bad oil temp, or the worst, bad engine.

but check them 1 by one, I dont want you to end up replacing the engine like 10 times, then you find out oh its just *fill in the blank* (some minor crap)

 

well im going to bring it into the dealership monday and let them diagnose it. but ill check those... What honestly do u think it might be?

 

good thinking,

and new motor..

just a guess, what do i know..

beers

 

any one else have any more opinions or similar problems like im having?

 

is it blowing any smoke as well?

 

not any i have seen. but the engine is making this unsual high sounding pitch and not running smoothly

 

..the marbles-noise you can hear; does it that sound grow proportionally to car revving. or the sound is pretty constant?

 

it grows proportionally to car revving.

 

Well based on what I've heard I would say its most likely part of your exhaust, not the motor. If you'd blown a seal, you'd be seeing smoke and a lot of it. Also, from your footnote, you'd have 3rd part exhaust parts fitted. Could be the cat, but I'd bet it is a muffler. Some baffle has come loose and that screws the flow of the exhaust air and will tend to kill the car. Can you lie under car a bit and knock on muffler(s) see if anything inside sounds loose/rattley?

 

well i check that like u said lucifuge but nothing was wrong.. So i went out and ran it , the sound wasnt their anymore and it had the power like normal. So now i got to wait until tommorrow to see what mazda says.

 

well im not suprize mazda said theirs nothing wrong with it and they couldnt find anything. so this means its going down the wrong path

 

I remember another guy posting about "marble sound" and mazda technicians running some engine tests and saying everything is fine. I think they had to replace his engine. Please search for his post in this forum. I think I remembered reading it in within the last one month.

Try searching for "marble" or something.

 

yea i know what ur talking about i found his thread and its almost like mine. i dont know what to do. i feel like selling it before more problems.. but that might be stupid

 

drive it and get it hot.. when it starts acting up drive it right to the dealer and do not shut it off.

take a master tech for a ride with the problem.. this system works well..

beers

 

ah that sounds good . they said only way they know what the problem is if its happening right their like u are saying swoope but didnt think about doing it like that.

 

I am sure you should be able to reproduce the behavior. Also talk to them about what problems they should look into. Some times you have to spoon feed

 

the problem is when i took it in , it was running like normal and the exhaust wasnt making marble sound. but when i took it home and test drove it little more i cound hear it a little so idk

Its like it reset itself but is just going to come back quicker.

 

u think if i did a mistake and didnt put in premium it would cause this problem?

 

nope.

mine runs fine of 87.

beers

 

damn u lol...u think this problem will come back or just a fluke... i need opinions on the situation, thanks swoope thou
