Gen2 3SGE unstable idling. Thu, 08 December 2005 04:33 Go to next message
Hi all,

i think my gen2 3SGE is having weird idling problems.

Mostly happens during a cold start, it will idle at 500-600rpm and the car feels like its about to die. however when the engine starts to gets warmer, it idles at 1Krpm and it occasionally idles at 500rpm from time to time when the engine is warm - hot.

What can be the cause of this?

Cheers,
Chopin

I think having air pockets in the cooling system usually affects the idle. some people have exprienced simular problems after doing a coolant flush.

Also maybe your cold start switch could be on its way out, causing it to run lean and not idle properlly when cold-warm

Dunno if the Gen2 has an idle control valve like the Gen3, but if it does try pulling it out and cleaning it up. They tend to get full of gunk after a while which plays funny buggers with the ECU trying to control the idle speed. Carby cleaner is your friend.
