Question about 1992 Pontiac Grand Am
I have narrowed it down to one of the possibility one injectors is going bad. While driving the car it has just died . you can stop turn the switch off a few seconds and it will crank up and run, or have to wait longer and it may run fine.or it may do this several times. A mechanic told me i could have an injector going bad causing it to die .How do i chech the injectors to see which one is failing

as far as the bogging and dieing,it sounds like the tps.a simple trottle body service would fix that.for your new problem you need to some test before pointing to a salution.start the car and cover your tail pipe.as pressure builds it push you hand off.a clogged cat will put to much back pressure on the engine.i would un plug the mass air flow sensor and try running the car.this will turn on the check engine light.check your air filtter and plugs.also check your wires.a nother test is a coil strees test.(you have to go to a shop for this)if the car runs ok with no load but spitts and sputters in drive you may have a openning coil.checking with a meter only works if it does not run.last but not least while you at the shop,have them check your timing.a faulty cam sencer will bog the car down with bad timing advancement but not throw a code.
hope this helps,remember to keep it simple,expensive elec. parts are not always the problem

I'm leaning toward a bad crankshaft sensor. There's a couple of experienced GM guys on here, so we'll pass it by them first just to be sure.

some cars have this problem when the intake manifold is loose or drawing air or the roteror cap may be defect, to check your manifold ,with a cold running moter spray a bit of starter spray (with eather) along the intake manifold , if it's leaking the moter will increase in rpm.

Is the security light on? If you have spark and fuel, it should run. Any codes? Could be bad crank sensor or cam sensor.
