Doubt it's the O2 sensor.More likely an issue with your IAC(Idle Air Control) motor.Quite often they get plugged up with carbon and stick in position.

SOURCE: engine stalls when restarted idles up and down and stalls

I went through this scenario while working in a toyota sienna a few months ago and it ended up being the battery. When battery supply voltage starts to drop the PCM will limit voltage to certain areas.

SOURCE: rpm 2500 to 3000 when you start then goes down 1500

In 99% of the cases of GMs doing that it's the Idle Air Control motor, which you already changed. But changing it does not always fix the problem. First, if you bought the new IAC motor second hand, change it again cause last time i had to change mine 3 times before i got one that worked OK. Second, if it was bought new and/or your are 100% sure the IAC is working fine, then you probably just have to much carbon deposits where the motor's tip and the intake manifold meet and are supposed to seal up, preventing it from closing normally and giving the engine too much air, cause the high RPM idle. So take the IAC out again, clean the opening, lip and everything you can see and get into around that area, with a cue-tip and some contact cleaner, or lighter fluid or rubbing alcohol to get all the carbon deposits out and you should be ok. If not, then the problem probably resides in the car's onboard computer.

If it ran beautiful I don't see why you installed CPS. ??? 

The CPS and CAS should only be replaced if the car is stalling or shorting out. I just changed the CAS on my 95 Talon but only because it was cutting off like I turned the key off. 

If the only thing you did was change the CPS then it's not lined up right. Every car is different but the CPS usually has to be aligned.

01 Kia Spectra When I start it cold it stays high idle. Have to press the accelerator to bring down the idle When shift into gear it hesitates to go It feels like it wants push gas through but putters

Ok that to me sounds like you need to clean the throttle body it easy buy carburetor clean just srap a little inside the throttle body n clean it that will help you the problem is the trottle body gets dirty sticky and won't idle good n stall remember don't put to much. Just a few spats inside the when you put the hose back it might take a few minutes to start because of the amount also don't accelerat it to high when it start good luck

High idle then stalls as soon as i put my foot on the break iac? would cause that how do i fix it?

It appears that the high idle and stall is occurring because you have a leak in the brake booster unit. When you put your foot on the brake the vacuum side of the diaphragm is subjected to air pressure and it there is a fault, that air is allowed straight into the fuel system which causes a massive lean out and the engine stops. Simple test is to disconnect the brake hose to the manifold and securely blank it off. Start the engine and apply the brakes . If it runs ok then that will be your problem

Please Help!!! Replaced ECM and truck immediately dies

Have checked the idle air control valve. If stuck closed it will not allow air to bypass the throttle therefore it will start and stall.

I have a chevy s10 2.2 2003 truck and one day it ran about five miles. then stalled. it started back up idled fine but put it in gear. stalled again. had to get towed home replaced the fuel filter,truck...

When you press on the gas when the truck is running, does it rev up?

Did it die while driving down the road (foot on the accelerator) or when idle? - If so, try cranking it and get your RPMs up to 1500-2000 RPMs and put it in drive (with your other foot on the brake). See if it will continue running if you never take your foot off the gas.

The idel on my 1992 chevrolet lumina 3.1 euro goes high then drops down low in park or in gear what is problem

Could becaused by a few different thing's . Map sensor , idle air control valve , a vacuum leak . Having the vehicle's scan data viewed would probably pin point the problem . Do you know what scan data is ? Is what a professional tech uses to find problems .
084 Engine Mechanical Tests Scan Data for Vacuum Leak
007 Idle Speed Problems Scan Data for Idle These kind of test's are what seperate week end DIY'ER's from a professional tech.

If you put your foot on the brake and your car stalls, that is a symptom of your brake booster going bad.

For it stalling on the freeway that could be a few different things, Idle Air Control Valve, the Mass air flow sensor

My 2001 dodge grand caravan 3.8l cuts off when i shift from park to any gear and the transmission fluid i checked from the dipstick is black and metalic looking

so it idles fine as long as it is in park. when you shift it into gear it stalls?

Does it feel like if you had a manual transmission and you let out the clutch with your foot on the brake?

if you are in a place you can do this safely without hitting anything try starting it while the transmission is in neutral. After it starts put it into either drive or reverse with your foot off the brake. Does it start to move, then the rpms start to drop fast and then stall?

Again if you can do this in a safe place what happens if you do the above and as soon as it goes into gear you give it a little gas? Will it move and stay running until you come to a stop? If yes the torque converter is locked.

Unfortunately from the description of the fluid and this symptom your likely looking at replacing the transmission.

The break cylinder in your engine goes into a item that looks like a pie. it is a big cylinder. This controls vacuum in and out. The reason it stalls is because this item is bad. I had the same issue and my son and I reoplaced it and all is well. So from the master cylinder it connects to this item. I apologize I forgot the name of it.
I would highly suggest you take it out and take it with you to the autoparts if you intend to DIY. The reason being is that depending on what month your care was made the main piston that attaches to your break pedal from there comes in two different sizes and I learned the hard way that this is the case...
Hope this helps.
