Hi,I bought a 2005 impala,3.4, a few months ago and I am sorry I did.I had the intermediate shaft replaced(common problem)felt like the steering wheel was coming apart at times.Then the service engine light came on.took it back to dealer and they couldnt find the problem.Had fuel injection cleaned.Then security alert came on message centre at times,while driving.Then my car just wouldnt start at times.Maybe a few hours later it would start.maybe not.Took it back to the dealer and they couldnt find a e,the car would start there.no messages either. It may never amount to anything other than a minor annoyance. If you aren't noticing any real problems other than the noise (and this is indeed the problem), I wouldn't worry too much about it. I had assumed it was just the age of the car that was causing the ping but when I happened upon the intake air issues and fixed them, the ping was fixed as well. In my particular case, the car seemed to run fine although I had engine ping at high rpms. Mine only happened on cold mornings as well. Start making note of the outside air temps when this occurs and see if they are close to being the same. You are only hearing it intermittently because the outside temps are affecting the way the components are adjusting to get the fuel mixture optimized and the mass of the air being pulled through the system.

Think of it as the type of sound of blowing across the top of a bottle. What you might be hearing is the air being pulled past the components in the intake (between the air filter and intake manifold).

What I believe happens is that as the parts wear, they don't function up to full specs. In my car, I believe it turned out to be the Mass Airflow Sensor or a component of the intake system. I had a similar problem with my '94 Mercury Cougar.

How To Diagnose Problems If Your Car Won't Start Has anyone had this problem w/the 3800 V6? Any advice? I'm hoping that if the battery doesn't do it, the car will start failing so the shop can fix the problem.

I have heard that a bad battery or one that will soon fail (or one that is defective) can possibly cause this (the battery in the car is 4 years old), so I might take it to a shop and have them check it and maybe replace it anyway as this would be the cheapest fix that I can do myself. Luckily, she was able to coast it a half mile to our driveway. We thought the car problems were consistent (always starts when when cold, sometimes won't start when warm, but will eventually start when engine gets cold), but it threw us a curve the other day when the engine stalled while my wife was turning into our development. We were hoping that it would start failing more often, especially when they had it (it always started for them) as they can't really do much as long as it always starts for them. They don't want to just start replacing parts as each repair can be costly with the fuel pump being the most expensive. They said it could be the crankshaft sensor, ignition module, or fuel pump. We took it into a decent local shop, but they told me it hasn't thrown any codes. It will sometimes eventually start after numerous tries, but will always start when the engine cools completely. It turns over, but won't start (sounds like it is flooded). After it warms up completely, if you turn it off (to go into a store, etc.), and try to start it again, it sometimes will not start (happened about 3 times in the last month).

It seems to always start when it is cold. Thought I would post this here as the Impala can have the same engine.
