Some ignition questions

Thanks for all the info guys, not sure it's the module as you guys have mentioned but I have a new module to try, didn't break the bank so it's worth a try.....all else seems good other than the play at the distributor shaft & reluctor. Certainly could have been my firewall connector but that's all better than new now. One good thing that came out of my ignition problem is it lead me to fix my firewall plug and engine bay wiring..... That mess was sure to leave me at the side of the road one day. Sounds like my distributor is not the only one with some play in it but I think it needs to be addressed! Thanks again, I'll post the results of the new module soon.
