I have recently purchased my dream car (or damn close) a 1989 Supra turbo. It's beautiful, if a little clunky right now.
As far as I know the engine is completely stock - I have recently replaced the Struts/springs with an Eibach pro kit and Kyb GR2s
There are a couple of things going on I'm not too sure how to start figuring out. I'm an engineering technician, and I'm used to troubleshooting, so I know the process, but I just don't have enough knowledge yet to know where to start.
I have an occasional low idle - usually when the car has *just* warmed up, or when I start it after it sits for 20 minutes or so. I have searched for (and found) this issue, but not sure what to make of the advice that was given. Usually if I rev the engine a few times when it idles low, the idle comes back to about 750rpm. When it idles low after running for a while (seldom), it runs smoothly at 500rpm, I just need to blip the gas before engaging the clutch to avoid stalls, otherwise no problems.
This suggests to me that it's likely running too rich? But I just don't know, and I'm not sure how to test it.
The second issue is three warning lights come on intermittently (always together); handbrake, tail lights, battery. I know this usually indicates alternator problems, but it's new, and my battery stays charged. If someone could link a picture of where to test with a multimeter (I might be able to figure it out, but...) I can test the charging when it comes up again. Extra info - when these lights are on, the cruise won't work - the light comes on to say it's on, but the car will coast to a stop. Any suggestions on what to test first (and/or links to instructions)?
There is also a rattle (this one is a shot in the dark) in the upper rear passenger side - but not constant. It sounds like it's coming from behind the rear seat belt hanger. Any ideas?
Links to info are appreciated - I know these are issues that have come up before, and I have searched - sometimes the info assumes a little too much car knowledge - I'm very new to working on cars, so clarification or starting points is what I'm really looking for.
Thanks!

) and is touching the gas tank - the sound was transmitted through the tank, up the filler pipe and sounded EXACTLY like it was coming from the right rear strut.
