installed my ka24de the car ran for a week , it ran rough but it ran, so I went to set the timing with a timing light and I didn't even adjust the timing yet and it would start. The car sounds like it wants to start but wont, it has spark and is getting gas, the no. 4 cylinder is only at 50 psi the rest are fine, I think thats why it was running rough, but the should still run on 3 good cylinders, i haven't replaced the plugs, wires, cap, or rotor yet because I was waiting to burn all the old gas out before I tuned it up, the gas is three months old still looks and smells good. What is doing it any ideas would be greatly appreciated. Thanks in advance Josh
