Just replaced the valve cover gasket and plug seals including the rocker O-Rings, gaped the valves, put it all back together and fired her up and got a CEL code-4. I looked it up and it appears to be the crankshaft position sensor in the distributor...but why after setting the valves and replacing O-rings and such? Thanks for your assistance!

 

Because, Murphy's Law.

Check that the wiring harness and plugs into the distributor are undamaged and seated correctly. Whatever you may have touched last, check.

 

It never hurts like mad-mike said and buy some electrical parts cleaner and spray our the plugs to ensure they are clean.

OK, thanks for the advice guys. I will try to review what I did yesterday and see if I can locate what happened. It was getting dark and I was getting tired buy the time we got it back together.

If I can't fix this distributer (1991 internal coil) can I use a distributer from a 1993 external coil? If so will I need a timing light? Any other issues I should watch out for when changing from a 91 internal to a 93 external?

Cheers
