My vic first stalled on my way home , I was at a light , and when the light turned green , I pressed the gas and it stalled. To get it to crank back up I had to give a little gas .It would stay running But as soon as I pressed the gas to go , it cut off.
I replaced the egr valve ,cleaned the passages, replaced both o2 sensors , replaced tps.
Its been sitting a while but , It cranks right up normally and you can give it gas and its fine, but when it warms up thats when it will stumble and die if Ipress the gas pedal down.You can start feathering the gas some before it dies and keep it running, but if it dies and you try to start it back up , you have to get it some gas toget it started.
I hope I gave you enough info, any suggestions will be appreciated

Thanks
Dave
