Car hasn't been started for over 2 years...can I expect problems from the EEC-IV????

You need the ACT and ECT sensors for the car to run. When my ACT went bad, I knew it because the car would not run at all. Once you get all the timing issues squared away, just do the standard resetting of the computer. The EEC-IV is always kicked in. That's what runs the engine. Leave the chip out until you get all the bugs worked out of the stock setup.
