I went to test drive a 2006 s2000 today and i thought the engine behaved very oddly.


The car felt like it was hesitating during a partial throttle acceleration in 2nd and 3rd gear anywhere between 3-5k rpms. This particular car when moving through 3-5k rpms had some flat acceleration when given gas and then shortly, it came alive. So when i gave it gas, it did almost nothing for a second and then there was a sudden burst of a power...likewise when vtec hits but we were under 5k rpms. It didnt do it every acceleration but i did few it multiple times. Ignition issue? Clutch slipping(didnt feel like it though)??

Ive driven s2000s before and i know that the acceleration is pretty much non existent under 5k rpms but they were smooth and slow until vtec.

 

Should have googled...

MY06 and up are drive by throttle, and have a slight delay if stock. Lucky thing is, it can be tuned out with flash pro which is $599. Also remember the S2000 doesn't have the down low torque of other cars

 

clean your IAC and throttle body
