Hi all,i posted under stalling and didnt get a response so ill reform my question. Would a faulty MAF cause the stalling problem that i mentioned in prior post and still not show up on diagnostic(no code). The only thing i can think of is to start replacing sensors until i get lucky but what one first? TPS,MAF.ignition module?? Desperate here guys..Thanks for any consideration towards this.

Very bad idea....costs a lot of money and might not even be a sensor.
Have you checked fuel pressure? Could be the fuel pump failing....like mine.
Check the spark plugs, what do they look like?
Could be a vacuum leak...spray some carb cleaner with the engine running around the vacuum lines...see if the idle changes.

Yes in my other post "stalling" i listed things that have been done ill list them again..these parts are brand new...fuel filter, fuel pump, crank sensor, iac motor, idle sensor,wires, plugs..i ran injector cleaner through it a few times, the car runs fantastic on highway with no missing at all its when i come to a stop it will stall but not always..had it to different garages that checked vaccum leaks etc and ran a diagnostic on it and everything comes up perfect..really confused here and that is why im wondering if any of these sensors ie maf, tpc, ignition module are known for causing this sort of problem without tripping a code?

something to check:

take your multimeter, and ohm out a little sensor inside your airbox. This is the intake air temp sensor, and if the sensor fails, it can cause stupid stalls and idle problems. If you get a value (dont ask what the specific resistance should be...) with the multimeter, the sensor is likely good, but its a good idea to check it first. Just unplug the weather connector, and measure from one conductor to the other on the sensor.

MAF's can cause this problem also, I have had both scenarios with my 3.8L. In all reality, I dont know how to properly test a mass airflow sensor without special equipment to measure it from idle conditions to wide open throttle.

From experience though, while the car is idling, go under the hood and grab the MAF, and move it around slightly, so the air flow changes direction flowing over the maf (I am assuming you have the 3.8L, not the 3800 engine). Doing this might make the air pass over a spot of the MAF that is dirty or faulty, and in turn cause the engine to run differently. If you can re-create your stalling problem under the hood by doing this, I'd say its the MAF. This is how I pinpointed my MAF sensor being faulty.

Some one else want to step up with more detailed diagnostics for MAF's?

Thanks for reply, concerning maf i unplugged it and cleaned connection with contact cleaner and plugged it back in then idled car and tapped housing with screw driver but no change at all in idle. i will try to test the weather sensor and let you know what the result is. i spoke to a friend who said he was having the same problem and he bent the throttle where it connects to the arm on the throttle body and it cured the problem, i suppose it would be the same as adjusting the idle screw but i my mind that ism't solving the problem only band-aiding by jumping up the idle which in turn will be harder on transmission when shifting from p to d.The car will stay running at stops if i feather the gas peddle so im thinking throttle sensor but i dont know if that sensor is that sensitive to actually control idle in drive, the problem is very erratic like i said sometimes i can come to a stop and it will sit and idle no problem in gear(r or d) but then other times as soon as i stop it dies unless i do a mini brake stand at a light or stop. I really appreciate the reply and please keep the ideas coming and yes i have a 3.8 with 1G3 vin not the C

pull out your maf and get some c&c electrical parts cleaner spray the shit out of the 2 little metal pieces that go accrost and dont touch the just let the stuff evaporate off use like 1/2 the can on it i bet it makes your car run a hell of a lot better also have you checked your map sensor they go bad also and cause crappy idle
