Interesting. I have found that someone else has had the same issue with his 93 and had traced it to a faulty thermal sensor. There is a sensor for cold starts and one for warm apparently, which i guess sends the correct mixture of fuel and air to get the thing going. The warm sensor might be faulty which is why warm weather causes it to struggle.
Most vehicles are fairly close relatives, parts like sensors may differ in name, but have the same purpose. The list of manufactures that use the same system is fairly long. Link:

They even missed a few less exotic makes like the Ford Capri. A few set ups will be different due to different, manifolds, throttle bodies, and other such things.
One of the other problems with valves that send fuel. Ethanol is corrosive and combines with water; aluminum and rubber does not like the stuff. With rubber it creates a petroleum paste grease like substance, that will muck up the fuel system. Despite my Spur, knock on wood, running well. My next service will be: changing fuel lines that are rubber, along with fuel filters and all the sensors, etcetera. Finish with flushing the fuel tank. Ethanol on the West Coast of The USA is almost unavoidable.
