I had similar issues with my Essex engined 6A and found increasing the idle jets by 5 thou improved things considerably. No idea if this works with the 2.8 although two jets cost only a few pounds and fitting takes a couple of minutes.
Which masks the symptoms. :w

Latest. Did the brake cleaner test and no difference. Son James (ex-Scimitar Coupé and now Nissan 350Z) took her for a test drive and found she drives beautifully. I think my problem is that I have been spoilt and made lazy (nothing new) by the Rover BRM with its 148bhp VVC engine which will pull smoothly from RIDICULOUSLY low revs. The Scimitar needs to be at about 1500 rpm. You'd think I'd know that after 24 years of GTC ownership .... :oops:

The 2,8 is noticeably less torquey than the Essex - and the 2,9.
But mine was surprisingly lively at all speeds (quicker than a 2 litre Calibra with similar power)
I think the superb Stainless Systems exhaust helped, with its very long primary pipes.
Sounded like a V8 ...

PS and a Solex carb :w

Mine has a lovely stainless system, including manifolds, too. But I've never thought of checking the length of my primary pipes. Is that rude, Chris?
