Why does your 2009 Tacoma have a random rough idle when you come to a stop?

Answer 1

I have exactly the same problem with my 2007 Tacoma, 24K miles. I don't have any other issues and the truck drives fine. My guess is if that we took it to the dealer, 1) they wouldn't be able to reproduce the problem or 2) they will tell us it is normal.

Anyone else have this problem?

I have a 2011 Tacoma 4.0L with 11K miles on it with a similar problem. It idles randomly/rough and is a bit underpowered (especially with a trailer). This is a condition that 'happened' at once at about 8500 miles. The first dealer told me I had water in the gas. The second dealer said the same thing. But, after driving another 2000 miles with the condition, they took a closer look. I would agree, its slight and perhaps a dealer wouldn't notice, but this is my third 4.0L Tacoma so I am very familair with how they should run. I had a 2006 and a 2008 prior to the 2011. I would highly suggest taking it in. My truck is scheduled to be looked at by a Toyota Field Representative in late January 2011. I hope they can fix this soon as I like the truck, but this is certainly not correct. Don't take 'water in the gas' as an answer, but be polite. Feel free to contact me if a dealer wans cross references. I think there are several of these problems out there, but Toyota doesn't know about them as they are slight and dealers are chocking them up to them being slight or user problems as this problem doesn't exibit engine codes. BTW, I did have mine shut down on me twice while on the highway while passing vehicles up a hill at high speed. Dealer can't recreate as it happened out in Wyoming where the speed limit is higher than where my dealer is located. The dealer has opened a Toyota service ticket on my truck. I'd be curious to see if anyone has an answer. They checked the fuel mixture, the spark plugs and the gas tank... no answer yet. I hope the Toyota Field Rep can help.
