Hi y'all.....

I am a long time lurker, first time poster. I have a 92 ZR-1 that has been sitting inside for a few years that I am finally putting time and money into. When I put her up, I was having overheating issues and backfire and stumbling issues. I have the plenum off and have changed all plugs and plug wires, as well as look for disconnected vacuum lines, etc. I am seeking wisdom and input on two things:

1. While I have the plenum off, what else should I tackle while there?

2. What else should I change/ fix/ inspect on a car that has been sitting for a bit?

Thank you!
