When the car engine is warm I have a 50% chance of the engine stalling when starting. You will get the engine started and it reves up and down between 1-2 rpms then stalls out completely. Thought it might be dirty fuel injectors and put in cleaner this didn't work. Thought it might be bad gas. But it happens with any gas that I put into vehicle. Notice that it sounds like the engine reves really high then quits. Its like its flooding itself out. Doesn't happen all the time. But when it does it will stall out on average 5 times. The fuel injectors will fix itself when you switch the car into gear. It will rev at a constant 0.5-1 rpm. My repair so far for this is as soon as it gets into gear to switch into gear. Have to wait to see what the mechanic says.

So my car keeps stalling and I thought for sure it was the fuel pump. Got that replaced and even replaced the fuel line and wow $1000 down the drain. I got new spark plugs and numerous tows costing over $200. Got a tranny flush anf fuel flush....didn't help. Now I called the Chevy dealership and I said I had a problem with my car stalling, the first thing the guy said was, "do you have a Malibu? If you do, it's the anti-theft passlock. It's happening to almost all Malibu's and it's going to cost about $800 to fix." WTF?!?! After reading all of these complaints, even if I DO fork out the $800, it's not going to fix it permanently! I was driving with my 6-month old in the backseat and I stalled in the middle of a busy road and I got hit! So now, my insurance went up cause of all this $h!t going on! If Chevy knows this is going on and they aren't doing anything about it, can't they be sued for selling cars that they know are faulty?! We need to get this recalled or something! I'm afraid to cut the yellow wire people are talking about, just in case they do FINALLY have a recall on this passlock bull$hiznit. (yeah right)

Any fuel delivery part on this vehicle is prone to complete failure. The fuel pump quit after 75000 miles, (it makes an awful whine prior to quiting, maybe a week to a month of life when that starts). The pump is a really cheap plastic unit (like everything else in cars these days) and be careful when installing a new pump, a good percentage of new pumps are faulty and will give the same problems. I had to replace the pump twice in two months. The engine wants to run horrible, like its missing badly. From what I understand the fuel injectors fail miserably as well and mine already have leaking problems. Any additives to the fuel (fuel injector cleaner for eg.) will cause the plugs to foul up and cease to fire. I had two plugs that looked like they had never fired at all and had wet fuel on them when I had replaced them, whether this was an ignition problem or flooding im not sure. The most current issue is the slight smell of fuel in the cabin like the engine is flooding out, this im not sure what can be the problem (fuel injectors?) approx. $700 spent un-successfully on repairs.
