KANGAROO HOPS!
Discussion
I believe this is called shunting, something my car doesn't suffer from at all luckily.
Lots of info on the forum if you search for shunting

Usually caused by incorrectly set idle control screw, faulty stepper motor, and can also be bettered with a better induction hose system apparently.

Cleaned and reset stepper idle. Before the K hops started revs would sometimes drop to less than 100 and engine would stall. Getting good sparks, 15mm on Gunson Flash Tester. Fuel pump is working ok on start up. No shorting sparks seen under bonnet in a darkened garage even when revved. Will check with Rover Gauge. I believe Paul at FFG reported this sometime. Will send a PM.
Hi, this is my first post in nine years of using this forum to keep the Tvr running as it should do. But an answer to shunting that I’ve never seen posted is what happen to mine. The car has always run fine with very little shunting at all, until the other week, when it barley started, kangarooed, shunted, would not idle nicely, stalled at junctions, basically ran like a dog but still had good power at the top. The reason was that a screw/s holding the vacuum advance onto the distributor had vibrated loose causing the lever to disconnect from the retard/advance mechanism. All now fixed and locktighted, now runs great with no shunting. Worth checking.
Thanks every body. Interest much appreciated. Have reset ECU using battery cut off switch. No fault codes shown by Rover Gauge apart from just the once, not repeated, Low fuel pressure (23) Fuel pump making the correct noises on start up but will check connections tomorrow including the blue socket relay. Will send upload images of Rover Gauge readings when PH have got them working again.Yes we are in guesswork mode.

Bloody hell, that is some serious lurking james_cWelcome aboard at last, and some useful advice for the OP to consider.
And now you've broken your duck you shouldn't wait so long to post again.
2 things poke out- 1) try the AFM in direct mode- it should be 32-35% (32% for a 3,9- 35% for a 5ltr). Alsocheck the fuel trim in long term- the short term is not cycling around a central point, so its running rich all the time. This may be reflected by a 100% long term trim, which means its run out if adjustment.

Thanks Mark. Will do, when it get's cooler. Yes a plug is very sooty.Gassing Station | Chimaera | Top of Page | What's New | My Stuff
