I am at the 92k mark on my car and it will drive just fine, but recently when coming to a stop light, the idle will drop down to one bar and I can feel the motor shaking, but after im at a complete stop it will come back up to 1k.

Im guessing its the spark plugs and imma change them out tomorrow. I hope its just that and not the coil pack.

Anyone else experience this as well?

 

Do a search and check the FAQ, this is probably the most frequently reported issue in s2000s.

I fixed mine by cleaning the idle air control valve and resetting the ecu. I got about 30 qtips full of black soot out of my IAC.

 

I recently screamed for help with this problem. I fixed it by changing out the throttle body. It's something to do with your TPS. Bad TPS will make it do this. Mine seem to go away after I changed mine out. Simple non permanent solution would be cleaning out the throttle. I did this first time and it went away for awhile. Hope this helps
