When driving my car, warm or not warm it likes to stall out on me. I can be driving on the highway going fifty five and it will stall out on me and die. When I come to stop sign or stop lights it doesn't want to idle or stay running. Replaced the iac and a few other sensors (can't remember.) also cleaned out the egr and it ran great for a couple hours but slipped back into it's ways later that night. Only code that popped up when hooked up to a scanner was quad driver #4 failing. Doesn't die every time I drive it. But does stall/ spit / and sputter every time. Also my rear right turn signal flashes on the left rear side but flashes just fine on the front right side. Any ideas?

Try playing with the ignition key (when safe to do so) when driving to see if you can stall out the engine.

When the engine stalls can you get it to start back up?

When it starts stalling i usually try to put it in neutral and rev it up to keep it running. When it does end up dying it usually takes a couple tries before i can get it to start up. And even then it still sputters and I have to give it gas to keep it running. Can't seem to figure out what's causing this. What you mean by play with the key switch? Like once the car dies and start it while it's still in motion?

Yes, start the engine (in park) and wiggle the ignition key all around softly to see if stalls out.

Next, try spraying carb cleaner or starting fluid on each of the intake components and wait a second to listen for an increase in engine speed with the engine running. Spray each hose connected to the intake manifold and gaskets. If an increase in engine speed or the engine runs better at idle this is an indication of a vacuum leak. Taking a few seconds in between spray will help isolate the location of a leak (if there is a leak).

You mention quad driver #4 failing...
Do you know what the number was that is associated with it (example 28) if so let me know what that number is, because it will help me to find more information that the vehicle's computer has found wrong with the engine.
