Monday got here at last!!!!
Discussion
Thought Monday would never arrive! On the road at last. Always wanted a Wedge but never driven one till today and it was definitely worth the wait!!Always spent money on bikes, not cars, until now. After all the Jap missiles my last bike was a Buell XB12S Lightning. Loads of grunt, a bit off the wall, totally different to everything else, individual and ten tons of character.
Remind you of anything with four wheels??
I have to say I'm definitely smitten. Never had more fun on four wheels than today. Totally addictive. Didn't want to put it in the garage tonight. Got withdrawal symptoms already and the weather's gonna be crap tomorrow (sobs)
Just one question: Do they all run on when you take your foot off the throttle. Takes ages to drop to tickover which makes the brakes feel worse than they obviously are cos they're trying to stop the engine as well. Any comments appreciated.
Hope to meet a few of you soon at the various get-togethers. Weather permitting Goodwood on Dec 6th is on the list of reasons to drive the new toy.
Yours happy!
Congrats on your new car! We're all addicted too.
No, they shouldnt run on. V8 actually has rather good engine braking on overrun. I suspect you have a pixie in the engine somewhere...
It may be a fault with the overrun valve, which allows a small amount of metered air past the throttle plate on high plenum depression (overrun) to enable overrun fuel to be burnt properly and not end up banging its way down the exhaust and shattering shop windows. Its a sprungloaded valve, and it might be badly adjusted. It sits on the rear face of the plenum top.
Any other thoughts, wedgers?
Actually its worth doing a bnch of checks on the air and fuel systems on the wedges to make sure theyre in top fettle. There is a lot that needs to be right for the Rover Engines to run totally correctly.
Which model have you bought? I say all of the above assuming its a V8?

Thanks for the info. Yes it's a V8 in a 400SE. My thoughts were that it may have an air leak. I suppose the item you mention would create the same effect?No, they shouldnt run on. V8 actually has rather good engine braking on overrun. I suspect you have a pixie in the engine somewhere...

Well done Mike. Know the feeling very well. 
The high idling can be different things depending what injection system it is. If it's the later 'Hotwire' system then it's probably the stepper motor sticking a bit. The stepper motor controls the idle by allowing more or less air in when the throttle is closed. It's at the back of the plenum. Just a matter of un screwing it & giving it a clean. When you put it back just remember it has to be air tight.

If you haven't got one of these then you have the 'Flapper' type injection system.

Ah, yeh, could be a faulty EAV (extra air valve) if its a flapper. Basically theres an air manifold that goes round the plenum supplying air for various purposes, and if it springs a leak, the idle speed will go up as excess air is getting into the plenum.
The Rover engine is prone to air leaks. A lot of the vac hoses are just push-on jobs, but I have started jubilee clipping them to be sure.

Seem to remember the seller talking about a stepper motor so guess that I have the hotwire system. Will check on the motor condition.

Hotwire doesn't pop and bang on the over-run (shame) whereas the flappers definitely do.
Also check that throttle linkage, return springs, cable etc are all running freely and correctly adjusted.
Check the timing isn't too far advanced.
The only time you should notice raised tickover on the Hotwire is when the engine is still cold, and then it will gradually lower in 'steps', say when sitting at lights, etc...hence the 'stepper motor'.
Eta: Just noticed it's a 1991, so a Hotwire it is. Congrats by the way.

Mine is doing that too. Looks like my first DIY job on the wedge is in order!
Congratulations on getting your wedge, lets have some pictures!

Thanks for the info. Just checked the V5. It's a 1990 not '91 if that makes a difference?Also check that throttle linkage, return springs, cable etc are all running freely and correctly adjusted.

Looks really nice!
Look forward to seeing it at Goodwood.
Not seen one with parking sensors before!
Believe me you're not missing much. Always bleeps loudly when engaging reverse and sometimes doesn't switch off. It'll either be fixed soon or the wiring's spaghetti in a bin for sure. Doesn't seem in character either to be honest.Not seen one with parking sensors before!
Weather permitting see you at Goodwood
