what a pita. what size is it anyway?

9/16 and you can purchase a special wrench for it at any parts store. I usually move aside the EGR solenoid to make it easier.

Ya, on the TPI engines you have to remove the coil with 2 7/16 bolts. It also holds down the EGR solenoid. Get them outta the way and you're good to go.

Don't forget to disconnect the computer advance wire on the pass. side cowl area if your adjusting base timing.

I use an extension and a 9/16th or metric equivalant, crows foot wrench. Import sets run about 8 bucks a set at your local HF store.

I have two distributor wrenches, probably not designed for this car, but neither will work because of the coil placement.
