Anyone have this kind of problem? It seems lately (the past week or so) when I first start the car in the morning, it starts out idling very low for a few seconds (kinda like its gonna die) and then it seems the ECU or whatever kicks in and the idle goes up to normal. This seems rather strange to me on a MY2000 S2000 with only 16,000 miles on it. I've never experienced this kind of symptom on a "new" car. Yeah, sure my '91 Prelude does that too on occasion. But then that car a hell of a lot older, too. I don't know. Is anyone else out there experiencing anything like this at all? Again, being a new car I wouldn't expect this type of behavior from it, but then maybe all is ok and I'm just worrying about nothing. Any ideas, guys? TIA.

 

Can you hear if the air pump is coming on when you start it? Right after the car starts, you should hear the high pitch "whir" come on, then cut off a few seconds later. You may also want to check your spark plugs. If you drive a bunch of short distances, they may be the wrong heat range, which could be fouling them out.

 

Ever wonder what the dealer might have to say about it?

 

just give the accelerator one pump before starting ....or after starting just blip the accelerator a little bit.

 

Not sure whether it is the same for you, but I had a similar problem. I topped up the oil to full(it was at 3/4) and the problem went away. Strange.

 

I used to have some rough idle problem and someone suggested that I should reset the ECU. You might want to try that. I worked on my case.

 

How do you reset the ECU?

 

Pull fuse #25 for about 30 seconds. It's the 3rd one down from the top on the right bank of fuses by the driver's left knee.

 

Cool, thanks xviper.

 

had the exact same issue with mine last spring.

x-viper's suggested cure above worked for me.
