What is the idle speed for a 2.4 99 GASE? My friend just bought one and its idling rough.

Because they are telling him thats too low and it should be around 1000 for a 4cyl. that didnt sound right to me.

Trying to remember...
The last 4 cylinder I had idled around 750 rpm.
It was an old 1985 cavalier with the 2.0 litre engine.
Light years different from the 4 banger in the GA though.

The 1000 you were told sounds a little high, but would be in the range.
My GAGT idles around 675rpm.

900 rpm. 2000 2.4L.

Yup around there.

On a '98 Sunfire GT 2.4L engine it is hard to tell.
The Rpm gauge is only marked in the 1000s.

But it definately idles much faster than the 3400 V6 engine.
