Injectors and stalling

You can have them checked at any garage some charge some do not. You would have to call around.

Basically their are 4 things that keep an internal combustion engine running. Gas, Air, Spark and Compression. If u do not have all 4 of these then your car will not run.
If your car is bogging down that means its either getting too much fuel and not enough air or too much air and not enough fuel. Or theirs a problem with the ignition source. Have your spark plugs, fuel injectors, fuel filter, air filter, airflow sensor, idle air control valve, EGR valve and maybe even your Engine coolant temperature sensor all checked for possible problems. All could cause these problem if not working properly. Timing might also be an issue so have those belts checked while your at it.

Good luck,
Joe
