hi guys,

i have mazda 626 V6, it works great except at early cold morning. It will start fine but if i am at the light and car is in drive but i am pressing breaks and waiting for light to turn off....it jerks 2-3 times and stops. It will start again..but will to the same thing couple of time after that. To avoid that i had to keep it racing. It won't give any problem later.

I took it to dealer ..he said he need to see the problem..which doesn't happen every day and un predictable..so really couldn't do any thing about it.

Any kind of help will be appreciated. do you think i need to increase car idle speed


Thanks
