Check for loose throttle body or TPS. Or vacuum leak. Cracked or broken vacuum line.

Code says system running too lean Bank1 and at stoplights I have to put car in neutral or it will stall


Lean Bank1 can be attributed to a faulty oxygen sensor or by unmetered air entering the system. A comon problem with the protege is cracks in the plastic air intake hose after the MAF which sucks air in that is not registed by the car and thus make it run lean and idle poorly
.
Another comon problem causing rough idle is the EGR valve being stuck because of carbon deposits, this will usually throw an EGR related check engine light but not always.

I have a 2002 vw gti golf with a 1.8T engine. We had it stall out on us at a stoplight so we took it in and they replaced the vacuum lines and said the problem was fixed. It's not it continues to stall...


simple test
start the engine and let idle
if idles ok , then put you foot on the brake
if it stalls ---replace the faulty brake booster
as with all faults in a cars
have the fault codes read first to avoid unnecessary waste of time and cash

I have this problem on my 88 mk2 vw golf, when you come to a stoplight the car starts to shake a little, but once you get on the gas it disappears, other than that she gets up and goes.


motor mounts sounds like it may be your problem. The motor will shake and stuff, and if they are bad bad, it may break more.. But yes,in order for a motor to work properly, it needs to be mounted tight for all of the moving parts. It can sound like it's stalling. Other than that, I'd suggest a bunch of other things Throttle positioning sensor for one. , sticky EGR, fuel filters, AIC Air idle control. I would say wait and see after mount is fixed, but if you price these things, you may find them cheaper than you may think. Good luck let me know how you make out. Cheers from Nova Scotia

06 ford focus stalls on stoplights and stop signs, more often then none. it starts t idle hard and have to press on the gas to even it out. Also my ac blows hot air and i can hear the compressor clicking...


sounds like the a/c is low of freon if the compressor is cycling that often due to low pressure. the idling problem sounds like a bad idle control valve. is the check engine light on? if it is and a p0171 code(system too lean) is present you should check for vacuum leaks.

1989 Cadillac Sedan De Ville engine stalls when air is turned on...tries to take off when stopped at stoplight..sometimes dies while driving..


It sounds like the idle compensation circuit for the engine is dirty or faulty. Have your car checked at a shop. have them check the idle air motor for dirt or malfunction. It could be that it only needs to be cleaned or replaced.

The compensation circuit adjusts the idle/slow speed of the engine. The air conditioner puts a load on the engine and this circuit adjusts the engine speed to compensate. Also, when the car is cold this circuit adjusts the idle speed to prevent stalling and help the engine warm up faster. I hope this information helps you.

Check engine light on with a P102 code. The vehicle is a 2007 Mazda 5. The engine kind of wants to stall out when idling and wants to turn off when stopping at a stoplight.


Most likely u need to pay attention toward the MAP ( airflow) sensor. Common cause in Nissans. I know u have Mazda, check ur comprehensive warranty status, if valid , take it to the dealer.

My 2002 camry stalls after running for 5 min. and...


My 97 CAmry was stalling at idle. Sometimes at stoplights or even when comming to a stop. Ran fine most of the time except at idle. It would shut off like i turned off the key. Found out the coolant sensor was shorting out intermitinly..Disconnect the sensor and sending unit if not sure which is which. The check enginr light will come on but that could be the stalling problem.

2001 Ford windstar stalling problems. After


have your idle speed sensor cleaned,also checkd the air flow sensor located in the air cleaner housing,you best bet is to have it scanned for PCM soft codes(codes that wont turn on the check engine light on)

Coming home and engine stalled at stoplight. started back up drove home, it wanted to stall at every stoplight. When it almost stalls and you accelerate it sputters. it has 65k miles.


It sounds like the vacuum line has a hole if you stop at the light and you have to hold the gas down a little to keep it going that is one problem it could be.
