Well, I'm ready to call my intermittent timing retard/acceleration lag fixed! 200 1986

After a couple of years of troubleshooting (and thinking I had it fixed 20 times) I think I've finally fixed my intermittent lag in acceleration.

I know as soon as I say this it will show up again but I'm pretty sure this is it.

the female electrical connection on the green wire from the O2 sensor was not tight enough on the male spade connector of the engine wiring harness.

it must have been just loose enough to make decent contact sometimes and lose it others. I know from experience that when your O2 sensor signal fails to get to the computer the vehicle will try to wait for a signal for awhile (while performing badly) then go to open loop mode where it just uses a default setting which basically runs OK.

my only question (and suspicion that this may not be the cause) is how did it always reset upon restarting the vehicle and run fine until the next time?

anyway, it's been good for about a month and a half after I crimped down that female connector so I hope this is it.
