What controls the idle on our R's, and how can I determine if it is operating correctly?

Cheers.

 

Let me guess, it idles a little high, like when you come to a stop? Then all the sudden it'll drop to 750 out of nowhere?

 

Yeah, mines does that too....LOL

??? Whos gonna explain this one?

 

Acura told me is was completely normal. My brother has seen this in his GSR and in his S2K. Seems like a normal issue with these VTEC engines. I got three different opinions from 3 diff. mechanics at different Acura dealers, and they also told me it was normal. One guy said something about computer regulating fuel mixture, lean/rich, leading to higher idle in certain circumstances.

 

I remember a post from a while ago saying that the alternator runs higher with the lights, radio whatever draws a lot of amps, he said that the older R's burn out the alternator easily. That was what I read dont know if its true. Anyway the idle control valve or the throttle cable can control idle.

 

Here's my guess....in no particular order
1) ECU
2) vacuum (which is low on Spec Bs)
3) idle control screw on TB

when the engine is slowing down on no throttle the unburned gas is creating pollution, so the quick jump in idle just burns that stuff off... Perfectly normal..
