Strange things with my Impala 3.4
Hi guys. Sorry i was to busy last month. Like i mentioned before i still have my same problems(cat symptoms), major loss of power and hard shifting. I think nobody gonna belive what i have right now. Alredy 2-3 month i do not have any SES light. I was driving 100 miles per day. I have 97000, 3.4,2003.
Not long ago and today i notice this: when i have 1/8 or even less gas left in my tank, my problems is dissapearing. I have a car same like i bought it. Everithing seems to me fine. I think this is only isue i have to figure out. Million times i chekd my fuel pressure and it was fine. Mabe its fuel flow or something bad with fuel delivery? What you think guys? You can find a lot of my posts on the same problem, and i think this is it. Any help apreciated. Thanks STEVE |

Re: Strange things with my Impala 3.4
I have Alldata, so i think its not gonna be a problem to change something. But i dont know what. Can it be vent pipe, or restriction on feed and/or return pipe(i mean pressure is good, but maybe flow is bad).

I would inspect the tank vent system.
