Answers: Maybe check the coil, you could have a fruitless connection and that's why it intermmitant.
1st stale the engine is a straight 6 cyl, not a V6...
As far as the engine stalling when you let sour the gas...
Sounds like a too low of RPM problem, if so...
You may hold a bad AIS motor, or even a on the blink TPS sensor.
The 1st thing I would do is to verbs the throttle blade. You can take past its sell-by date the throttle body intake tube off so you can look into it and see the blade. You can after take a toothbrush and some carb spray and verbs the blade and bore of the throttle body. This service rarely get done, and is somewhat important.
This will verbs up and allow the correct amount of air to intervene by when the throttle is closed. This saves the computer from have to compensate for any restriction. I have also see this service fix a low idle - dieing problem oodles times.
Now, back to your problem...
With out checking your vehicle to see what generous of fault is cause your problem, wether you have an electrical, or an air-fuel type of problem make if some what difficult. But if you clean the throttle body blade you can also check the AIS motor a bit. This would be an nouns valve that let air bypass the throttle blade when needed. With the upper air intake tube off and the engine idleing within park, you should hear air going into the throttle body. Now if you pass the engine a rev, and then permit idle again, that hum will be louder for a second before coming to a complete rot. Also the RPM's will be about 200 RPM's during that second past coming to a complete idle.
This louder resonance of the air going into your throttle body since it comes to a complete idle is nouns going throgh the AIS motor, or air bypass spigot. The computer controls this, and what it does is lets the fester come down a bit slower than if you were to snap the throttle friendly and closed. This lets the stand still come down smoothy and preventing a stall, or too low of an idle.
Another process of seeing if the AIS motor is working, is, while the vehicle is idleing in park beside the air tube sour, you can spray a small shot of carb spray into the throttle body, just a touch, as to not destroy the engine.... And you will hear the engine stumble a bit then hear the AIS motor crack up and raising the rot by its self, and then pay for down.
If all i.e. now ok, and you still own a problem, you may want to have it checked out a bit. I own seen a bleak TPS sensor (throttle position sensor) cause this sort of anticlimax of stalling, although not too common, but it can come up.
dirty fuel filter,faulty fallow air control spout,faulty fester speed actuator,faulty decline stop solenoid,throttle position sensor,or electronic spark control module.
