I have a 92 Chevy Cavalier Z24, I have changed the plugs,wires and put a bottle of fuel injector cleaner in tank but it still stalls out when I stop when the car gets up to normal temp range. I bought the car and not sure if it sat awhile before me. Not sure what else to do for it, please help????

Re: stalls out when up to temp
I suggest to perform the following : take out the throttle body usually it acumulates carbon , blocking the air passage, even if this wont solve the problem ,you should clean it anyway , check the PCV valve , clean it or replace it , replace the fuel filter , I mean since you just have this car and dont know how much maintenance got. since you already replaced the spark plugs & wires, Im sure that doing these extra steps will resolve the problem , IF NOT , then we have to say that the FUEL INJECTORS need to be cleaned professionally or REPLACE. hope this helps AJ

Are you sure it's the coil pack. I need more info do you have a check light if so go Auto Z or Advanced A or any big box auto parts store and ask them to plug your car in and get code for problem. I'm bettering your problem is not a coil Pak. It has no moving parts it just sits their practicing Tesala's law of induction, more like you have a bad spark plug cable, dirty fuel injector, bad spark plug or all 3. FYI a Fuel Injector is like an eletronic- solenoid operated Windex sprayer. It shoots a fine mist into the cylinder for ignition. If the Windex bottle (injector) spray nozzle gets clogged up and dribbles instead of misting it causes poor combustion and can shut you car down, go find a bottle of SEAFOAM injector cleaner an poor it in you gas when your down 1/4 tank then run it out of gas (just kidding) go as low as you can go. To check spark plug wires, get an empty Windex bottle, fill with h2o and go to a dark place and spray cables. You may see a little lightning storm or your engine may stttttuter. Good luck ,PS cleaning you injectors every 3k is not a bad idea due to the age of you vehicle, good luck Bret PS driving a97 Buick mysel I know what older cars can do
Could be numbers of things, get your self a bottle of fuel injector cleaner, pour all of it in the gas tank, and fill up with high octane 92 or 93, run it for while and see if change anything. Prob: Bad O2 sensors. MAP sensor, dirty plugs, bad/clogs injectors. If you have a high miles 100k change wires,plugs, good tune up would be good.
It could have bad gas or plugged injectors in it. Try a bottle of water remover and octane booster in the tank to keep it running, the next time you fill it up put in a bottle of fuel injector cleaner. I would also change the fuel filter, as any water that it caught has probably started to rust it from the inside. The other thing to try would be to loosen the gas cap after it stalls. Does it **** in air? if so mice have made a nest on top of the gas tank and plugged up the tank vent. You will have to drop the tank to fix this.
Check to see if you emission system sensors are plugged in, such as the air intake sensor which is plugged into the air hose at the front of the engine. Another possibility is your gas cap. Replace it, its very cheap. If it only occurs at higher speeds it may be clogged injectors. Dump a bottle or two of injector cleaner into the gasoline tank after a fill-up. You might also try some octane booster which is methanol and will mix with and help remove any water in your fuel tank.
give it a oil change and put a new fuel filter on it. you might have to change spark plugs and spark plug wires. also put some engine and fuel treatment. if that does not work put about 5 gallons of premium fuel in.
