car is slowly killing me... *UPDATE* fixed! Options

[Scott-thundercat]

Okay so i've run the gammit of crap for this car. new cap, new rotor, new points, new condensor, new plug wires, new coil, adjusted valves, replaced BENZ fuel pump with late 914 fuel pump (thinking maybe too much pressure was problem). replaced all fuel hoses, replaced fuel tank (no kinks in lines), replaced fuel filter.

questions are thus- when i start the car it runs, it runs rough but it still runs. let it warm up- can drive it while cold- when it warms up it dies and wont restart for quite some time. plugs dont have oil on them but do have some signs of way too much fuel. this sounds like it could be the CHT sensor. Question- i have a black wire coming off of what looks like the CHT sensor slightly in front of the rear cylinder on the passenger side's spark plug... doesnt connect to anything- dont see where it could connect to... where does this wire usually live?

also going to bypass the Cold start injector cause i think it might be leaking into the engine fueling the oil.

the engine runs quite rough (like at least one cylinder is missfiring)- until i let off the throttle from around 3K rpm- then it runs perfectly (but at 2000 RPM) for a few seconds before becoming rough and crappy again- why?

this car is slowly killing me- i've found so many problems and fixed em only to have more left. i'm going to head down to go work on it-(parked at a gas station where i limped it to while trying to drive to my new apartment).

if anyone has some great advice or wishes to help please call me at five three zero 220 four zero 33... sorry for the wierd way of writing it- dont want any autoscanners to pick it up.

found a leaky fuel injector on the pass side front cylinder. found what looked like some of the pics of the CHT on the block aft of the distributor.... (clearly not cylinder HT) with a wire that went right into the wire harness... maybe oil pressure? still could not find any wires that the black one matched with. tommorow i'm going to put one of my spare fuel injectors on and see how it works. i remember looking over a wiring diagram for this car (70 1.7 D-jet) that showed a temp sensor hooked to the cold start injector as the switched ground (the cold start injector had a wire coming off that was the right length to match up to the CHTish thing... i put my multimeter on the CHT- and it was open- so it seems like it could be a switching ground for when it gets cold out... i dunno- very odd. none of the things i look at for the DJet have the same stuff as my engine...

thanks for the input guys- i'll look again tommorow in the light.
