i have a 1993 mit. Eclipse 2.0 non-turbo and im getting intermittant spark on cylinders 2 and 3.I have already changed the computer, coil pack, and power transister module(all used parts from wreacking yard) its always when I first start the car this problem occures. Once the car is started it never fails. When it does fail if I try long enough the spark will come back. Any ideas?

There is one output for 1 and 4 whreas 2 and 3 has another. If the sensor gears are faulty, they could miss when at 2 or 3.

You're welcome.

Check the gap between sensor and sensing gears. Look for uneven/wavy movement of the sensing gears and chipped teeth.
