180sx really low idle

[Maloney]

well hope someone can help me with this... my 180sx starts up and idles grand for about 2/3 minutes but then the idle drops to about 500 revs and the exhaust warning lights comes on. engine doesnt cut out? there is a blow in the turbo elbow gasket could this be the cause?

thanks lads

sounds lik your lamba sensor id say lad,try swap one with someone and you should no

[Maloney]

thanks man. and if its not the lamba sensor any other ideas wat it could be?

[topdog]

Maybe an air leak some where. Try your vacume hoses and maybe your intercooler piping

[Maloney]
