Got my blk/blk used 01 S2k recently, it had only done 7500 and I didn't feel like waiting for months!


Today I decided to go for a quick run to the shops and as I pulled out the driveway I started kangarooing violently down the road!! I checked for the usual things, like is the handbrake on? am i in 1st etc. but all were ok? any ideas??

I've also noticed that at slow speeds in 1st and 2nd, the slightest touch of the throttle jolts the car! it feels like i'm a learner all over again!

 

Aside from the S2000s very light weight flywheel and sensitive throttle there are known problems with the kangarooing/bucking problem. Board opinion is not unanimous but suggestions include faulty MAP sensors (easily rectifiable), heat soak/hot air ingestion caused by sitting in traffic, the engine altering its mapping into an economy setting during long periods of idle.

The ubiquitous search facility ought to turn up quite a few threads on this, try 'bucking' as a search topic.

Edit: I give the throttle a very slight blip prior to engaging the clutch when setting off from a standstill at lights, in traffic etc. Not a boy racer rev mind! just enough to bring the revs slightly above idle. I also only fill with Shell Optimax and between these 2 things have never really suffered from the phenomenon

 

thanks for the tips,

I'm still on the full tank of petrol my dealer gave me when I collected the car. Perhaps he's filled it with regular unleaded? next fillup will be optimax

Congratulations

I will keep an eye out for you around here and will certainly give you a wave if spotted

yeah the flywheel/clutch combo takes a bit of getting used to!

- 2 months down the line I still go for the odd hop but I blame that on wearing Cat boots while I'm driving

- Congats on the car - a mighty fine choice!

 

thanks guys, i'm starting to get used to the clutch now, but still jerk it a bit.

if i see any of you around i'll be sure to wave

 

I had my first experience of Kangarooing last week. It was quite a shock.

It happened when sat in traffic on a warm day, as several other people have mentioned. It was quite violent, but went away as soon as I got moving.

As I'm now aware of what happens, I'm not too worried, but it's worth being aware of if it's not happened before.

This is NOT the same as the sensitive throttle/clutch when you start from cold.. it's much more violent.

It happens to most of the cars at some time. Some people experience it more than others. On my car it is very rare.
Since running on Optimax I've had fewer engine management glitches. My car (99 model) does really not like regular unleaded. I now only use Optimax as do the majority of S2000 owners who can get it.

I can vouch for the fact that Optimax makes a difference in lesser vehicles. We currently have my brother in law's 1.0L Polo parked on our drive and I take it to work from time to time to keep it running. It was a pig to start for a while, so I've given it a couple of tanks of optimax and it runs much much better now. No problems starting and it almost feels fast (for a wind-up-elastic-band model).

 

It only seems to happen if I let the clutch out too quickly in 1st or 2nd at low speeds.

If I control my left foot, it never happens. Seems to be more related to driver skill rather than a car fault to me.

 

After driving auto Legends, it took me a while to avoid kangarooing when driving the S2K, but when I changed to Optimax from the Dealer's 95 RON fill-up itt was amazing how much my technique had improved.
