Could be an idle air control problem, or possible vacuum booster trouble, have also seen the baffle broken in the GM tanks and when you brake hard the engine dies. Fill the tank and try it, if it doesn't do it the baffle is bad.

Problems accelerating


the engine tickover is too slow when the engine is cold its running on cold start, ie:choke,, after it warms up the engine slows down this is what is causing it to stall in gear,, get some one to hold the brakes hard on and with the engine running in gear ajust the tick over till its reving at 750 - 850 rpm the revs will go up a bit when its out of gear,, before you pick a gear to go into push the foot brake down to stop the car lurching,,,

I have a 94 sunbird it keeps cutting out when stopped what could it be the fuel pump or fuel filter someone put a bad bottle of gasline to help clean the jets


if it stalls at or near idle do this.
Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

1995 jaguar xj6 stalls once you stop at the stop signs


Look for an IAC sensor (motor) Idle Air Control.
Usually located on side & front of throttle body. Not 100% sure which type you'll have but if you have pintle type (pointed end) Remove it, spray it well with throttle body cleaner as well as port it came from, and retry. If it cures it temporarily & starts to do it again, replace it.

94 spirit stall when I put on the brake


Do the procedure below, it should cure the problem
Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Tighting an emergency brake


I believe the 94 Sunbird's have rear emergency brakes. The rear brakes are drum brakes and it's very hard for them to lock up but should slow the car down to a stop and hold it from moving when at a stop.
The way they work is, the emergency brake cable pulls on the one of the brake shoes to the brake drums on each side so you only have 50% of your braking power to start with.
If your brake's are not holding when it's at a stop position, the brake shoes are warn or glazed over and need to be replaced. 
You can try adjusting then by backing up a few times like say 7 times and giving it full brake application. That should adjust the brakes if the self adjusters are still working.
Good luck and hope this helps
