EST Connector setting code 42

I reset my timing yesterday. Since then I have been getting an intermittent code 42 like the connector is loose. It happens when I hit big bumps then goes away when I hit another, but sometimes it will set the SES light and give the code 42.

I have daignosed it as being the EST connector due to the fact that it had no problems before I unplugged it.

BTW- I unhooked the battery after the adjustment and again a few times to reset the code. It still comes back once in a while though.

TIA

Try hitting it with some contact cleaner.
