I have a 92 mx-3 gs 1.8, and well...what is the problem when the car is in neutral, and the rpms dip down to idle, like normal, and then it bounces, and then cuts off. i'm not that car inclined but something isn't right, although it doesn't really do it when the weather is warm????????? what is up? anybody help please!!!!!!!!!!!!!!!!

check your vacumm hoses...umm yeah [img]shrug.gif"%20border="0[/img]

same thing happened to me once. And I found out it was one of my spark plugs were going bad. replaced it and it was fine.

distributor, ecu, spark plugs/wires, vacuum...could be a lot of things. Does the temp go up really high if you drive it around??

I just had the same problem and what it was, was a combination of things. First thing was the EGR valve, it was not opening properly. This part is really expensive I think $500.00 and you can only get it through Mazda unless you go through a scrap yard which I did and got it for $75.00. Unfortunetly it takes about 3 hours to install because of the tight fit. However, this only helped the problem a little and I took it to Mazda to have a dignostic test. They found three codes cleared them, and said it was stalling do to a carbon build up in the intake manifold, throttlebody, and the fuel system. It cost me about $150.00 to do. You can clean out the throttle body yourself its not hard, but the fuel system flush must be done at Mazda for about $100.00 They have to hook it up to some machine. But I would suggest getting a dignostic test done first your computer might be just tripping some codes and after the clear them it might even be better <P>Good Luck

how much costing on that diagnostic test?

BRO, <BR> check your air intake hose for rips. They're hard to see on the car.. take the hose off and flex it while watching the accordian part. If there is any leak at all after the VAF, your idle will bounce so drastically, it will kill the car.

Ya, the exact same thing just started happening to me. Turns out there was a rip in my intake hose [img]shrug.gif"%20border="0[/img]
