I'd probably start checking your plugs, wires, and timing (in that order) next. It's possible that your plugs could have been fouled, and the ECU running rich while in limp mode might have fouled them more. Also these cars are notorious for leaking oil into the plug valley, so you may have oil soaked plugs/wires.

When you check your timing, be sure to check your valve timing before you check your ignition timing.
