An intake snorkle is a good idea anyway as it ensures the airbox only takes air from outside the engine bay. In my case I bought a new MAP sensor and it was fine again, while others have cured it with intake snorkels and cooling mods.

I have some logs from my PLX when the car was kangerooing and there was basically no fuel going in, and some very screwy readings from both sensors. The kangerooing I believe is to be ether IAT (intake air temp) or MAP (manifold absolute pressure) heatsoak. No car ive ever owned does it this bad, and the ECU should easily be able to cope with the flywheel weight. It has been said that the car will kangeroo becuase of the light flywheel - I dont subscribe to that view. You have been driving the car a while, you stop at a junction waiting to pull out, you see your chance, boot the throttle and not a lot happens Frustrating at best, dangerous at worst if you roll out in front of someone! One person (simon prelude) also had a seized aircon pulley which cause a bad idle on his ISCV / AIC (idle speed control valve) misbehaving Idle and hesitation / kangeroo problems can be caused by the following: If your problem persists or gets worse then read on.Īll this info is based on MY00-05 cars - the 06 has some differences in its setup which im not clued up on (drive by wire throttle etc) Your ECU has to cope with changing ambient temps and pressures, and can simply be adjusting. Idle / Hesitation / Kangerooing / Misfire ProblemsĪs idle / hesitation / kangerooing / misfire problems and misfires seem to be a common problem on the S2000, and indeed on most cars, I thought I would construct a thread to aid people in diagnosing their problems.Īside from an actual problems listed below, these type of problems can just be a passing phase.
