Car shuts off when A/C turned on... - Toyota Yaris Forums

Howster · 06-26-2013, 03:21 PM

I was wondering if anyone has the specifications for fuel trims and O2 info for a 2007 Yaris? I am still having issues and purchased a Innova 3130C scanner. I just don't have a baseline for anything so don't have a starting point.

Now the only problem I am having is mainly hesitation on acceleration from a stop, but also sometimes at speed. Transmission seems to stumble when trying to go into passing gear.

It seemed to run better for a while when I put a new MAF sensor in it, and the hesitation was pretty much gone. However that lasted not very long. I now have the original back in. I have replaced the fuel filter, along with parts mentioned in earlier posts. Only thing I can think of now is vacuum lines and fuel pressure, although I don't know what the pressure should be. If anyone has an idea that would be sweet.

So many have helped with this and I am still dealing with this since I am not able to work on it except for the weekends. I would appreciate any info anyone can help with.

Thanks again,

Howster
