Ok here goes 1993 240sx ka24de 60,000 original miles here goes the problem car has trouble starting. The car will start with the help of giving it gas but when running the it idles from 400-1000 rpms and the whole car shakes. I've checked other threads and found alot of people haveing the same problems but never any solutions. The things I have done was checked the injectors one was a little off so I replaced it, I replaced the spark plugs and wires, replaced valve cover gasket, checked the temp sensor and the maf sensor. checked for vac leaks. The car is useing more gas than it should can go about 30 miles on a quarter tank nd the car has no mods. One problem I've seem to find is pulling the 4th plug on the injector has no effect to the engine doesn't idle higher and doesn't lose power. I unplugged the 3rd injector and hooked it to the 4th injector and still no change cause I do know the 3rd injector does fire due to unplugging it and the engine loses more power. The engine light hasn't come on so I have no clue any help would be appreciated...
yeah its running rich the exhaust smells like gas, i'm going to check the rings today.The only plug fowling out is number 4 and its brown every time. Hopefully ill chase it down soon sick of putting so much damn gas in the car
UPDATE: I changed out the fourth injector again with another one car ran fine for about a day, but know its doing it again what could cause me to foul out an injector so fast?
no haven't checked that yet kinda set the car on the back burner working on my twin turbo 300zx. Might put the Z motor in the 240 and put an rb26 in the 300z
