ignition problem?
I was wondering if anybody ran into a situation where when checking the timing, you get a good timing reading on the L1 coil, but the timing mark doesn't even appear when the timing is checked on L2? The light flashes, but the mark cannot be seen! Is the CAS off or something, as I thought L1 and L2 give the same timing readings? Any help will be appreciated.

I am definetly on L2, I even turned the clamp pickup of the timing light around on the wire, and it is the same! L1 shows the timing on the mark, but I can't even see the timing mark with L2!

Tried changing wires? Although honestly, there's no reason to check timing using L2. Just connect it to L1, time, and be happy. As mentioned, they're the same coil and fire at the same time.

I am trying to chase down a light running problem. The engine is rough between 1000-3000rpm, after that it gets smooth, there is alos a slight missfire at idle, so far all sensors/tune-up items look good!

There is absolutely no vacuum leaks, the plugs and wires are new as well as o2 sensor. I was not checking for spark, I was just making sure the timing was right. The car has 18 inch of vacuum at idle, and has lots of power, it just vibrates a little bit, and is hard on gas.
