Fuel injectors are high on my list of things to replace. At the very least, replacing the fuel injector cups and O-rings. Spark plugs and distributor cap are also a very good point that I had not initially thought of. What, specifically, is difficult about tracking vacuum leaks in these cars?

Taking it to a mechanic is not something I want to do from a cost standpoint. While I may be younger and with a low postcount here (lol), I'm also not totally dumb.
