video game tester?
well the shitty idle and dying will be from a vacuum leak issue, so get all that shite fixed up.. check out
this for a guide to most of the vacuum lines in there... and
this for more of em
for the electrical issues first check out your fusebox and make sure everything is still good, then after that
find yourself a factory service manual!! you they're usually at
www.carfiche.com but if not just wait a day or so and it'll come up, i just think their server sucks too much to have all of them up at the same time or something like that
check out
az's site for overheating fixes... first thing i'd try is taking a high pressure water hose to your rad and blowing all of the masses of dirt and leaves and shite that builds up in there...
also i'd recommend doing a full tune up.. fuel/air filters, plugs, plug wires, distributor cap and rotor, check all your belts and stuff, and perhaps if warranted get the 60/120k mile tune up done to it.
after that you should be good to go
