Idle at Start Up


Recommended Posts

I have a 2002 C4s coupe manual. Lately on cold startup it starts at an idle of around 700 rpms and when you hit the gas it dies. After restart it idles up to 1100-1200 rpms and then settles into the 700-800 rpm range and everything is good. The temperature here in the morning is 74 F as a low and 100 F as a high. It only does it when the car has not been warmed up first time start up of the day. It just started doing it over the last few weeks. I have always used Techron every 3000 miles to hopefully to keep the deposits from building up. I was told by my dealer that the cars are made to use 93 octane but here in the US we only have 91 at the pumps and this contributes to carbon buildup. The dealer told me this was due to carbon buildup and the gas needed to saturate the carbon before everything would run right.

Thanks for any input on this matter.

It's not too hard to clean the carbon from the throttle butterfly. It has been covered many times here - try doing a search.

Thanks Loren, that did the trick. There was not much carbon, but it looks like just enough to make it so the air was being disrupted or not getting through as much as it should on idle. What a simple fix. Thanks again for a teriffic website.
