My car is garage kept. It does the same thing, but very very rarely and random. I've had this happen only 1 time thus far. Car was outside, and after being driven around, then sitting in a parking lot. Freaked me out.

I've cleaned the maf recently with CRC. Did the plugs, new air filter, and techron fuel cleaner. Haven't noticed it yet, but engine still has that vibration.

Well, I think the only way to solve this problem is start the car and drive it away right away without waiting and pretend this problem does not exist at all.

Yes that is probably how it works for a lot of people. I know so many, that take off and the engine barely finished cranking.

Well, come over to this thread. Ripp might be on to something here. Going to give this a shot as soon as I can.

The manual does say that the car is designed to warm up whilst driving. And that extended stationary warm up is not recommended.................

For your information "Cleaning" a MAF is pretty useless if it is dead so the only real way to find out is to disconnect it (electrically not physically) and take it for a quick spin around the block. Just don't drive it like you stole it

I always drive it like I stole it. That's the reason for the V8. I had no maf codes prior, just cleaned it for the heck of it.

I am on the opinion to let it Idle till it goes out of Blue dot, and then drive slowly untill Oil warms up fully.

I get in, count off 15 seconds, put it into manual mode. Shift to 2nd, and go. Once the RPM lights turn off at 5K rpm, I put it into auto mode and just drive. I drive it easy till all the Tach/RPM lights turn off.
