Corruption

I just recently installed a greddy kit on my 91, with an emanage blue, took a bit to get it going but it's going. Now that it's running well, I'm having a bit of a problem with the timing. The gentlemen I worked with regap'd my plugs, but I don't think he set the timing to 8. Is there an easy way to check/set the timing? I also have a problem where when idling, it'll go up to 1-2k and slowly droop back down then back up. Sometimes it'll sit pretty at 850, but otherwise it has a mind of it's own. It also gets bogged down at high revs sometimes. I still need a proper tune, got the emanage with the kit already set for it, but I was wondering if there's anything I can do to make it better for now.
