Could be a wheel imbalance. you may have thrown a weight. also on front wheel drives the is a weight on the drive shaft, if that has moved or added weight/or lost weight it can make an imbalance at slow speeds.

SOURCE: 94 gme 350 engine. slow

Hi, can you give us more history? How long has this been going on and how did it start? It's definitely an air/fuel issue, but could be MAP sensor, injectors, etc. Is the engine light on? Is this throttle body injection? If yes, have you looked at the spray pattern of the injectors? Does it stall? If yes, have you verified no vacuum leaks?

My 98 mercury mystique is missing 3rd gear it goes 1st and 2nd fine but wont go over 30mph and no matter how high the rpm go it wont turn over into 3rd gear Help

The likely problem is the VSS or vehicle speed sensor. The transmission uses the speed from the speed sensor to determine the shift points. You should have the check engine light on it will probably show a code for the speed sensor. Hope this helps!

Can I engage and disengage the 4 wheel drive while I'm driving? At what speed?

You can engage from two wheel drive to four wheel drive at any reasonable speed though I find it's easier on the transfer case if you do that below 45mph. Lift you foot off the gas as you shift so the unit is not under stress. To engage 4 low, you should not be traveling faster than 5mph and then, only on slippery surfaces. When in that gear, it is not advisable to travel much faster than 25-30mph and never on dry ground.
