Good luck and keep it fun, if ya can.
Best tip I can give is to keep in mind that these are old cars, as in corroded electrics etc. That said, never rush out to by a replacement part like an ignition coil, MAP or other sensor etc until you've re-seated/or and or cleaned all related connectors. More often than not, someone will replace, say, an ignition coil and think it was the fix, whereas the car now runs again which will make he/she trash a good coil. Sadly the problem was not a faulty coil but rather the corroded connector/s that plugged into it. The act of swapping out the old one for the new one, cleaned the connector enough to make the car run again, at least for a few months.
