Is this normal? Uring cold start it goes to 1000rpm but when it's warm it goes down to 200rpm..

Everything seems fine to me, but 200 seems pretty low..

It's just about impossible to answer your question, without at least SOME information about the car.

Also, you would be MUCH better off joining a discussion/tech forum for that particular kind of car. There are many out there, and they have enthusiasts who are "into" that kind of car, like nobody here will be.

That said, 200 rpm is FAR too slow for a car to be idling.

1000 start up, on any car is ok, normal idle is no lower than 650. 750 for most is optimum after warm up and sitting in park, add 100 or so if ac is on. 200, should be stalling.

Are you going by the tach on the dash? If so my guess is that something's out of whack. As others have said, at 200 RPM it would probably die rather than idle very long.

I agree. Your tach is not accurate at that rpm, thats all

I don't think I've seen a car or truck idle any less than 500 RPM. 200 seems like it would be on the verge of stalling.

Anything under 500 and it would be stumbling and stalling. I agree with the others that it's most likely a problem with your tach, not the engine itself.

I agree with the "bad tach" posters. I'm no mechanic, but I've never driven a vehicle that would even give a useful tach reading below ~400 RPM.

Yeah I am...

But I don't think there's a problem with the tach accuracy.. The car feel like its actually idling low, it's a lean burning engine QG18DE
