This may be because the engine is not generating enough vacuum or booster size of your car is small.

To solve this problem there are following option.
1. Use bigger booster is available.
2. As your compan to tune your ECU.
3. Ask company to put vacuum sensor in booster, this basically cut off your AC when it sense that vacuum level is less.

My 1997 Ford F150 Truck,it shudders and dies unless I put it in park at a stop sign? we took it for analysis and they couldn't find the problem,

I have seen this symptom and it is caused by a leaking power brake vacuum booster, when you apply the brakes it creates a huge engine vacuum leak and this causes the engine to run lean and rough and die in some cases. Most likely the shop was looking for an engine issue when it was a brake related problem

2010 subaru forester engine cuts out

consider this
when at the stop lights , you will have your foot on the brake as it will still be in drive or in gear and you don't want the car to move
a simple test is to apply the hand brake to stop the car and don't touch the foot brake
if it idles ok but cuts out when you apply the foot brake , replace the brake booster as it has a vacuum leak that is causing the problem
you can do this test in the garage by starting in neutral and allowing the engine to idle , then apply the foot brake
iof it dies it is the booster

Large and small evac leaks? Truck dies at idle/stop signs. Any ideas?

if the problem is when you have your foot on the brakes at the lights ,I suggest that the vacuum leak is from a faulty brake booster
a simple test is to apply the park brake and not use the foot brake and if there is no problem then it is the booster.

What would cause engine yo die at a stop light and not start again. The engine almost turns over but doesnt.

engines stopping at lights can sometimes be attributed to a vacuum leak in the brake booster
test by idling the engine with the hand brake on and no foot brake then apply the foot brake and if the engine dies then it is the brake booster
hard to restart may be the vacuum leak if you still have your foot on the brake.

2008 bmw stop running when stoping 3.o engine

test the brake booster
start the car and idle with the handbrake on. If it idles ok then apply the foot brake
if the engine dies or stops --replace the brake booster
If the engine will not ilel without the foot brake check for a vacuum leak in --the transmission vacuum line , vent control lines or manifold leak.

Drive vehicle down the road for 20 minutes and come to a stoplight engine stops when you take foot off gas peddle and go to apply brake. To keep vehicle from dying you have to hold the gas peddle down

Have you changed the timing belt? or timing belt guides? How many miles? This does not necessarily have to do with fuel.... Could have to do with air intake or timing as well....

Car dies when brake is applied

Couple of options here. If it only dies when you have your foot on the brakes, then it's probably a vacuum leak on your brake master cylinder, It is a large hose running from back of intake to brake booster, with a plastic fitting for the hose to slide on. If you hear a hiss when you apply the brakes, that's definately it.
other than that it would have to be some kind of idle problem. If the car sits and idles fine then check the hose. Hope this helps :)
