Default Cold Start Studder Shake?

Ok, got in the Z tonight to take clothes to laundry. Everything starts and runs just fine, it's like 40F here.

Get back in car about 10 minutes after putting clothes in washers and it starts funny. Lots of gurgle and shakes. Can really feel it in the gear shift. Stays that way for the two minutes back to my place. let it sit hoping with temp increase it'll go away. It didn't.

Tried shutting her down and re-start. Didnt' help.

Anyone else experience this? It shakes worse than my 91 Toyota corolla.

Well, new news.

Started it up about 30 minutes ago and she ran like normal. So, there was definitely something wrong.

It kind of felt like it wasn't firing on all cylinders, but I would have thought something that severe would have set some engine light off.

It was bad, kind of felt/sounded like a Harley.

Getting my BOSE amp replaced this Friday, so I guess I'll bring it up then.

same thing after I started up my G35 after I was on vacation for 2.5 weeks. Then I jumped in my Honda and guess what....same deal. After it warmed up for about 5 minutes, it went away in both cars. Go figure

Well, I took her in on Friday. It seems she might have bad injectors. (At least that's what the dealer thought) They need to replace a couple of them. She'll be there until Tuesday at least. They had to order some parts.

She did get the new BOSE amp in her, but I haven't heard it yet.

I miss my car.

You'd notice it if you did. I started her up Friday morning and she was doing the same thing. on the way to work the check engine light came on as well. It was really bad.

At the dealer, it was still acting up, but for some reason when they took the plastic engine cover off, it stopped. That's why it's not 100% sure it is the injectors.

Who knows.
