If the engine revs up when you put it in park and now it is tugging when you drive as the rpms go up what might be causing this?
The most likely cause is a stopped up fuel filter. Replace it and if that doesn't do it, check the fuel pump preasure. If ok, it could be a stopped up cat convertor.
94 5.8 Ford Bronco won't start without Starting Fluid It will run ok until I cut it off and the same will have to be done again what could cause this?
It could be as simple as a leaking fuel pressure regulator that allows fuel pressure to drop when the engine is turned off, and it's not getting up to pressure when you try to start the engine. Try this: Next time the engine sits for a while and you're ready to start it, turn the key on but don't try to start the engine. Leave the key on for about five seconds then turn it off. Repeat the process, THEN try to start the engine. It might help but then again, if it doesn't you aren't out anything.

The distributor could be failling, there might not be enough fuel or air reaching the engine (too much is bad too), or your spark plugs/wires are damaged or not to spec.
What causes car to misfire at high speeds?
The spark timing might be too advanced. At high temperatures and RPM an advanced spark might cause preignition, and engine knock. That's only likely to happen if the engine is modified though. Other than that, check the air and fuel filters are clean, as the harder the engine has to work the more a clean flow of both is important.

Can bad timing cause your car to idle rough and vibrate badly while in gear?
If the timing is off a lot it can make your engine misfire and may not fire on every cylinder on every rotation. This can cause your engine to shake on its mounts and therefore shake your car, but usually at low RPM's. Poor airflow to the fuel ports can also make your car idle roughly. Might be a dirty air filter or the mass airflow sensor might be dirty (you can get throttle body cleaner for that). Also, low oil can cause you car to run roughly and labour a bit on hills.
Shaking steering wheel and engine light on?
The shaking wheel part suggest that there might be an engine misfire, the engine light on suggests that the computer is trying to tell you what's wrong. Connect the engine to a diagnostic computer to see what's going on. The computer can often give you hints to the real problem.
