Help - my S thinks it's a Kangaroo!

[S3 Kieran]

My previously trouble-free S3 started kangarooing yesterday on the Mid-Essex convoy. I thought it was my mate Paul's driving (let him have his first ever TVR experience in the driver's seat) but it did it to me on the way home too!

1st/2nd pulling away from standing or rolling start (fairly quick if standing start) and fuel/ignition appears to cut out intermittently causing the learner driver 'kangaroo' experience. The only way to cleart is dip the clutch and start again. Once going, I can cane it as hard as I like without a hiccup, but very embarrassing/dangerous when going for the gap at a roundabout.

Any ideas? Is this part of the mystery that is: the throttle-pot?

Nearly reversing into slamm at the traffic lights was not a fault of the car - this would be Paul working out where reverse is, at not the perfect moment! - sorry about that (again) Mel!!

Mine did this when I first bought it and it is the unmentionable bit

Disconnect it just to be sure, it will run ok like this for a while.

Thanks Andy.

I'm sure I read earlier threads saying that you should disconnect it, disconnect the battery for a couple of mins, then reconnect all, and it's reset.

Is this right, or does that just get you out of trouble till you can get to a garage and rip the bd out and replace?

Ran mine for 3 months with the pot disconnected and it went fine.

Forgot to add. No, don't reconnect the pot after the ecu reset. The fault lies with the contacts in the pot and a reset doesn't fix it. Leave it disconnected until you replace it.

Had similar problem on my chimaera, turned out it had a cracked pillar on the coil.Might be worth a check.
