Throttle body?
Can the throttle body go bad on aleros? ive made a post before how i thought it could be the fuel pump.. but im not sure and i have no CEL.. so its very difficult and it causes serious anxiety lol.. you can be at a red light stopped.. and it wants to try and go dead at idle.. its fine when it first starts... but after the car is warm is when it does it the most... ive changed everything else.. Plugs,fuel filter cleaned IAC.. but i notice even driving when accelerating it wants to be sluggish..

Bad fuel pump will usually do nothing at all. How many miles do you have on the car?

It hooks into the bottom side of the throttle body. If you can't find it, then let me know and I will either try and find a place to take a picture or ask my friend if they have one from when they had to change theirs.

Run it for a while at night and look underneath at the cat, if they are bad they turn slightly red from being hot.

How were the spark plugs when u pulled them out? Basic diagnostics here. Almost sounds like it's running rich (ok when cold cuz it needs the fuel, then bad when up to temp), maybe bad fuel pressure regulator or intake air temp sensor.

plugs had normal wear from having 80k on them.. believe they were the original plugs.. and fuel pressure regulator ive been reading about this alot and seems to have the same symptoms is this part real hard to change?

you have a vacuum leak. check every hose, look at everything that comes from the manifold and the throttle body.
for sure

no. checked for vacuum leaks already... we thought it was plugs is the reason they were changed.. has more hesitation while taking off more then anything.. figure it was fuel related..
