Have you replaced the fuel filter? also spray the inside of the MAF sensor with brake clean, there may be a particle of dirt on the sensor element.

    Yes the plug wirews also can cause this, do you think it misses or sputters? then the plug wires may be at fault. If it just bogs down it is most likely the fuel filter

Engine stutters or stalls after a complete stop upon engaging to go forward


You'll need to have someone scan the computer for the codes.
Most auto parts stores will scan for free in hopes of selling you some parts. Once you get the codes you can research them online or in this question.

1996 Pontiac Sunfire engine shakes and acts like it wants the shut off when at stop light.


Sounds like you have a bad cylinder...
This could be due to a number of reasons...
No spark at one cylinder, due to a bad spark plug, coil, or wire.
No fuel due to a bad injector
Bad cylinder with low or no compression

5 speed manual transmission wont shif gears while running


You probably have air in the system. You need to bleed the air out of the system so that it will disengage your clutch. The air in the system is compressing and, therefore, the slave cylinder can't reach the full extension.
