Question about 1990 Mazda MX-5

1 Answer

Engine occassionally stalls

Hi
I've just bought a gorgeous 1990 MX5 Eunos, and although it sounds brilliant, when you rev it- if you let it go back to idle it sometimes custs out. Has anyone got any ideas? I'd be really grateful as I have no idea what it is? Dont worry that I'm a girl, I know my way round an engine!

Thanks in advance

Sharron, Kendal

    it may be the air intake box/tune (I don't know what it is called). The motor mounts wear out, then the motor vibrates and the fan belt pully wears a hole in it, very small, but enough to change the air intake pressure, then it stalls when you are not giving enough gas...I am looking for a stock replacement part. It is fixed only with tape for now.
    Hope this is it for you too.

Hi, I just bought a tired Subaru Leone (1990) Station Wagon. Everything feels OK for the age of the car... but it accelerates like a boat. The engine seems great and isn't miss-firing. The clutch bites...


I think you`ve answered your own question.
The clutch sounds as though its on its last legs.
I would take it down to a local car mechanic ask him for a verdict on the clutch and anything else that needs doing.Remember you don`t have to take his offer,we are in the day and age of haggling.
Once its up and running subarus are so reliable a good choice of car.

Mx5, possible misfire, lack of power in low revs


Hi this sounds very messy if somebody has made a mess of things the only way to check it out is to get it to a reputable garage and get it checked over ,did you have the head pressure tested as a common fault with these cars is internal cracking of the head which can often look like a head gasket failure the only solution then is a complete new head good luck with this

1990 1.5l wont rev past 3500rpm's


Honestly I wish I could offer you more info, if it revs now that eliminates the convertor, only I can figure is when you got it to rev you were "blowing the soot out" LOL I hope I have helped you some if so please rate me accordingly.
