Even though I disagree with Wack0 about how picky the cars are (I have non-turbos in pretty friggin' good shape, just fix 'em when something new breaks) I agree with almost all of the fixes they recommended. Get the Bentley 16 valve repair manual. It's awesome! All you have to do is figure out which wrench to use. My bets are on a failed fuel pressure regulator (rear of the fuel rail, right on top), a seriously neglected fuel filter, or a fuel pump check valve (you can replace this without taking the pump out, it's just under the trunk floor). If you need to, have a shop hook the car up to some fuel pressure gauges and measure the pump delivery (running) pressure and the rest pressure. If the rest drops, you've got a leak, likely at that check valve. If the running pressure is sky high, the regulator's toast. If the running pressure is too low, the filter is clogged or the pump is dying. If both are okay, you may have fouled fuel injectors. As part of the tune-up, throw in a bottle of fuel injector cleaner, run it through (run the tank way down) and then change your fuel filter. The FI cleaner will dissolve everything in the tank and on the injectors, then the filter will catch the bad stuff, then you change it.
I was a little intimidated by my '88 (different fuel pump but the idea is there). I had to change the pre-pump (you don't have one) and I waited six months before fixing it. Two connections on top and a hose, pull the assembly out, two more wires, two screws, put it all back together, done.
If you think these cars are complex, try working on a new one. All of a sudden, you lose the ability to read off codes on your own (or buy a code reader plus hundreds of dollars' worth of software) and you end up with a control modulemobile with four oxygen sensors, teensy little electrical contacts, direct ignition ca$$ette$, cost-optomized parts, and no room anywhere to work under the hood.
Besides, no points or condensors! No timing or idle speed to set, the fuel filter's the size of my size 12 shoe, and it's built like a(n aerodynamic) tank.
