I was getting a rough idle when at a stop (accelerates fine) and got code P0354 so I changed out the #4 (front center) ignition coil. That fixed that problem. Since I have 120000 miles on my 2007 Sienna I also changed all 6 plugs. With everything apart, I cleaned the throttle body. In the...

My wife's '99 Sienna runs rough when stopped in drive and runs LESS rough when put into neutral and when I turned the A/C off, it runs smooth as if it does has not a problem. Any suggestions from the Brain Trust? All input is deeply appreciated. Jarhead

I spoke too soon at the end of my last thread. To recap, my 2002 suddenly started running unusually rough last week; I cleaned the IAC, but no change; the CE light went on with a misfire code in cylinder 2; I eventually changed all the plugs (the one from #2 did look bad, the gap had closed...

My wifes van has had the cel on for about 6 months, I knew the codes led to a bad A/F sensor in bank 1. I saw the price of the replacement part and the physical location of the sensor and nearly had to change my drawers. Van started running so rough had to pull it off the road, bite the bullet...

today I drove my first 08 in our search for a pre owned Sienna. It was very rough - like we were riding on pebbly asphalt. Will try another at another dealer tomorrow - but curious if this is 'normal' - our old Previa is a very smooth drive. Would not buy such a rough ride, this dealer had not...
