Starting problem with an '05 V-6 - Toyota Nation Forum : Toyota Car and Truck Forums

First off let me apologize if this has been covered already. Tried the search first but came up empty. My wife has a 2005 Camry SE V-6 with an automatic trans. Over the past couple of months we have had a starting issue. Does not happen all the time hence the dealer cannot pinpoint the problem. Sometimes the car will crank a few times and sound like it wants to start and then finally the idle smooths out. Only one time I was able to catch black smoke from the exhaust while it was sputtering (best word I could come up with for a description) and only one time the check engine light kicked on. The car has been in the shop numerous times for this and was only duplicated once. And of course it was when it was not on the diagnostic machine.

Various fuel system parts have been replaced, different brands of gas have been tried and the weather does not seem to effect this particular problem in one way or another. Any ideas since Toyota is at a loss? Thanks!

We will be going on our 3rd time with Toyota service on this problem.

From your description its hard to say - my 2 cents, one time i was having a similar problem with my old 85 nissan 200sx, it turned out the valve clearances were too tight. Although this sounds quite the long shot to be your issue especially in such a new car.
The clean- the- throttle- body -butterfly trick might be worth a try though - but really i'd just take it to another dealer maybe, since its probably under warranty

The odd thing about this is that we've hae the car since november '04 and this problem only started a couple months ago.

Fuel pump, regulator and some kind of clip. They did not go into detail about the clip. I'll have to see what the paperwork said.
