Tvr S1 2.8 idle and running issues

[buldysor]

Hi PH!
New to this, so please be "gentle"
Just got myself a TVR S1 1988 2.8 and it's having some issues running nicely
It starts half key but idling lumpy, engine is shaking and loads of petrol fumes
Once warmed up, it's worse, engine is more lumpy, and on the road it's very rough, shaking the hole car, at low or high speed.
There is also a hissing noise when running engine, but cannot find the air leak.

Already change air hose, 2 fuel pipes from the Bosch K-jet to injectors
Changed spark plugs, and ht leads look like new. The sparks where very dark on the top, but they didn’t look old.
Tried to adjust the fuel mixture with the 3mm key, but no results.
Checked all the wires, cleaned connectors

Any help would be appreciated, still have a couple of things to check tomorrow, but want to get this sorted soon
