i live in michigan and the weather here has been messed. for about a week it has been around 40 in the day. at nights it gets around 35 idn dont pay attention. but i notice when i start my truck that it runs a lil diffrent untill i get moving. i have cleaned the throttle body and stuff and that was diffrent. is there ne thing that helps take the condonsation out of my gas and the lines that works well?

 

its called Dry Gas comes in a bottle. but i highly doupt there is water in your gas heck i live 15 min from you and my truck is fine.

 

Iso Heet is also a good one to use. It has isopropyl alcohol, which absorbs water. Any water in your tank will go through the fuel system. Be sure to run the tank all the way down.

Iso Heet is in the red bottle. Don't get the Heet in the yellow bottle. That stuff is methanol, I think. It will prevent your gas line from freezing, but it doesn't absorb moisture, and hence won't extract moisture from the tank.

A classic symptom of water contamination is the engine power dropping off at high RPM. That's due to the water being stopped at the fuel fiter and preventing flow. Since your problem occurs at idle, water may not be your issue.

But hey, it is winter, and it never hurts to run a bottle of gas dryer!

 

so what might the problem be?

 

Hard to say what the problem is. In your first post of this thread you said it runs a little different before getting moving. We might be able to narrow the causes down with some more info. Bring it on!!
