Hello everyone, I recently purchased a mint condition Canadian built 1981 244 GL with the B23E engine and the Bosch CIS fuel injection, I've been wanting one of these cars for almost ten years and finally I got one up to my standards. There are few things that had been driving me crazy since I got the car tho, which are the idle, warm starts and excessive fuel consumption. When at idle you can notice that the engine shows a considerable amount of vibrations,which you can feel while you are waiting on the lights, it disappears as soon as you step on the gas. It starts right up when cold, but if you let it sit for more than an our and attempt to get it started, It gives you a hard time and when It finally fires up, it feels like a carbureted car with a flooded engine. Yesterday I had replaced the fuel injectors, since all my problems seemed to be related to plugged/dripping injectors, but for my frustration it didn't changed the old problems, even that the original injectors were nasty dirty. Now I can only considerate a leaky injector mount,since I only replaced the four injectors and their respective O'rings. Since I got the car, I had replaced the respective items: Spark Plugs Distributor Cap All the wiring to the spark plugs Fuel Injectors I also noticed that my vacuum booster hoses are not connected to the engine, but I had taken the car to a mechanic and he said it has nothing to do with the idle, he said as long as there is no emission regulations I don't have to worry about this vacuum booster(there's a illustration attached). Thank you all for your patience. Cheers
