TooMany, the wiring on my '81 Camaro has that same EGR bleed solenoid. I think the purpose of it is to bleed off some of the vacuum going to the EGR valve when the torque converter is locked. I have the schematics for the Camaro at home, I would imagine that it would be a similar control circuit on the '84. I think it's the same signal from the computer that drives the EGR bleed and the lockup, but I'll have to look at the schematics to be sure.

Short answer is I know it can be done, but I'm not exactly sure how until I look at the schematics. I'll check tonight and let you know...
