I know this happened to a lot of S2000 and I was wondering if anybody had a fix to this issue.Ive changed and calibrated the TPS, map whack with zip ties, cleaned IACV, Reseted the ECU, New airfilter, Cleaned throttle body and Im running a catch can.

Status of spark plugs?

Thanks!

 

new. but been through 2 track days. sometimes it drops to 200 rpm and tries to bring the idle back up and sometimes it stalls completely

 

going to try just replacing the map sensor and see if it fixes the problem

 

In that video , how long ago did you reset the Ecu?

 

actualy a long time ago before the last track day. I still need to reset the ecu from calibrating the tps yesterday.

 

going to change the map and reset the ecu asap and give an update.

 

State how you cleaned the IAC valve.

 

unbolted from the intake manifold and cleaned the 3 slots
