Car cuts off after I crank it up and put it reverse...if I let the car warm up then it doesn't cut off


Hi there:
The engine uses an air flow meter and any vacumn leakages would cause the engine to shut off. I would suggest checking the air hose for leakages, hidden cracks that would only appear when the engine is shifted into reverse.


When in forward gears, the engine would tilt to one side, there are no leakages but when shifted into reverse, the engine tilts the opposite way, ( old engine mounts tends to allow the tilting to be quite substantial) causing the air hoses etc to open up any cracks and allowing excessive air to leak between the air flow meter and throttle body causing the stalling.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.


Thank you for using FixYa, have a nice day.

My car keeps shuting off when i either touch the brakes and/or put it into drive or reverse. I am thinking it is the neutral safety switch and im not sure how to install it


The safety neutral switch is to prevent you starting the engine while in drive or reverse. It will not shut off engine, just prevent the starter from working.
Pressing the brake will affect the vacuum pressure of the intake momentarily due to the brake booster use of vacuum "pressure"
Shifting to drive will lower the engine idle speed, lowering the intake negative pressure. (Vacuum)
I would think you have a problem with the mass air flow sensor which controls the fuel mixture depending on the volume of air flow and sensing the vacuum level of the intake. Possibly just a minor vacuum leak at the mass air flow sensor. Maybe more serious problem. Check the small hoses at the MAF for rot or splitting. Im sorry I cant help more than that.

C220-manual transmission. erratic idling and sometimes idles up and down. Has been serviced and throttle body cleaned but still does this. Happens more often when the engine is warm.


according to your information it's faulty mass air flow sensor, check mass air flow sensor first, when the Idle rough just disconnect the air flow sensor wiring socket if it's better than when it's connected it's faulty air flow sensor, mass air flow sensor have fitted between air cleaner housing and throttle body, you can see wiring connector been connect on it you have to turn it anticlockwise and remove it. when you fix it back do the reverse order, if it's faulty replace air flow sensor. is this information helped you?

My 07 Toyota Corolla will start fine. It idles without problem, but as soon as I put it in drive it dies. 40% of the time it will do the same thing in reverse also. But 100% of the time once I put it in...

How to check if vw 1996 microbus radiator is


You must remove the bottom rubber hose from the radiator, and also the upper hose. Extract the radiator out or simply flush the radiator in reverse direction of water flow. If the radiator is clogged you can try to clean inside (chemically) or replace it. Flush the cooling system in reverse direction of water flow. Refit all in reverse order and after that purge air out of cooling system.

SECTION 412-01: Air Distribution and Filtering 2001 Focus Workshop Manual DESCRIPTION AND OPERATION Air Distribution and Filtering The new heating and ventilation system ensures even air distribution.
The temperature control and air distribution flaps are controlled by two operating cables. All vehicles have a recirculated air function, with the flap controlled by a servo motor.
Air is supplied to the windscreen and side windows regardless of the air distribution setting.
The clean air filter is fitted as standard in most countries. This cleans the incoming fresh air of pollen and dirt particles. It must be renewed after every 40,000 km under normal operation conditions, or after 20,000 km under difficult conditions. If no clean air filter is installed, a plastic grille is fitted over the air intake. This can easily be replaced with a clean air filter.
Air distribution operating switch
Face level The main flow of air enters the passenger compartment at face level.
Face level/floor level The main flow of air enters the passenger compartment in equal parts at face level and floor level, and a small amount flows to the demister nozzles of the side windows.
Floor level The main flow of air enters the passenger compartment at floor level, and a smaller amount flows to the demister nozzles of the side windows.
Demist/floor level The main flow of air enters the passenger compartment in equal parts at the windscreen and at floor level, and a smaller amount flows to the demister nozzles of the side windows.
Demist The main flow of air enters the passenger compartment at the windscreen and a smaller amount flows to the demister nozzles of the side windows.
Air distribution operating switch Air distribution operating cables
NOTE: The Bowden cables for LHD and RHD vehicles are identical. However, they are fastened to the air flap operating mechanism with the respective reverse side of their connectors.
The air distribution switch operates with two Bowden cables. The cables operate the air distribution valves in the heater housing.
To remove and install the cables, the rotary switch must be turned as far as it will go to the left. The air flap mechanism engages easily in this position, making the installation of the cables easier.
