The beauty of old cars is that you can normally "see" what is wrong. The 2.0E engine was running bad on idle and not that great when driven either. I spotted that the rubber section between air filter and inlet chamber was lose both at air filter end and indeed onto the oblong air chamber. Removed and checked air filter and replaced carefully making sure fitted tightly and no leaks. Replace plug leads as they looked worse for wear as well as the distributor cap. Both had serious corroding connectors and poor condition overall. 

Car now runs smooth on idle and is as I would expect it to be. 

Cleaned up some serious oil leaks around the power steering reservoir. The feed to the pump seems very loos so will change the clamp on the hose.

Engine bay cleaned up reasonably well. Found a dodgy connector to the distributor stopping the engine from starting, so awaiting a small brush and dielectric grease to try to remedy humidity getting to that connector.

Looks great 👍 🙂
