adjust valves and now not running well
I adjusted the valves on my 93, removed the plug wires and some of the distributor wires and now the car seems to be missing half a cylinder or so. Can't really tell until I get into third gear, or very low second. Checked all of the distributor connections and made sure the wiring order was correct. Loosened the plug wires and re-seated (is it even possible to get one of the plug extensions in incorrectly?) on all but the left rear, which isn't possible to get at w the heat shield in the way. Does it matter that some of the plug wires seem to run over each other leaving the distributor? Anyway, I am at my wits end cause none of this helped. I'm assuming that the problem is somewhere in the plug wires, since I have heard that the 964's are very sensitive to electrical. Does anyone know of a procedure to find out which plug is offending the system?

Could be as simple as...
Rick
When I change my ignitions wire to Clewett Engineering I got the same problem, 2 or 3 on the right bank did not fire up. Well it turn I tough I had seat the wire correctly on the plugs but even though they were tight with no play the whole right bank was not plug. I took me over 10 minutes to plug one... but once I found the correct angle the other on when in right away. Good Luck J.J.

One quick check I often do is run the car on one distributer then the other. Unplug one coil wire then the other. I do this to tell if the dist drive belt is still OK. In your case if the engine runs OK on one but misses on the other then you likely have a plug wire not seated . It will also isolate the top plugs from the bottom and help you narrow down where to look.

I did try both distributors separately and they both ran ok. Seems that, unless under load, I couldn't distinguish which way it ran better and, I believe that you can't run on just one distributor. I also tried using one of these spark wire inductor gadgets (they light up when you place them on the plug wire), but the wires were too close for me to distinguish which wire wasn't working. Maybe its somewhat intermittent, but it sure runs like you know what when under load.
