My 72 1800E recently developed a problem with hard starting when warm. The car starts instantly when cold but will not start once warmed up and then killed. It also has been running progressivly lean. I will richen the mix at the map sensor and it will be good for a week but then it will start to go lean again. I have tested the following.
1) Fuel presure at all r.p.m.'s 28 p.s.i. (good)
2) Resistance at engine temp. sensor (good)
3) Resistance at air temp. sensor (good)
4) Can not find any vacume leaks
5) Resistance at map sensor (good)
6) Triger contacts (good)
7) All 4 injectors are firing properly

Have not tested the cold start injector yet but will.
