Starting last night started running a little rough. Some vibration when accelerating. Starts right up but very rough for about one second. Usually parked outside. Parked in garage tonight hoping it runs better on the morning. Any thoughs?

 

Make sure you use additive in your gas.....

 

Which additive?

 

Gas line antifreeze. Avoids freezing and formation of water due to condensation, creating misses and hesitation.

 

Is it really needed, since 20 gallons from the pump already has 2 gallons of ethanol in it?

 

Was just a suggestion. Up here in canada I use it anyways. Especially if you're the type to park in the garage sometimes and other times outside. Such a practice is killer for condensation. That' what I'd try first... Add a bottle of gas line antifreeze and fill-up.

 

Thanks for the cold weather advise. I usually do not park on the garage. Wife gets one spot and my sons older car that does not like the cold at all gets the other. Plus I have a remote start which makes it easy on me. Not sure why but after sitting in the garage for the night and above freezing she is now running fine. Now to see if it happens again. Anyone else run into this.

 

Ethanol is horrible for engines especially in cold. Forms lots of condisation in lines. At my bros motorcycle store they use startron and they have a empty bottle with ethanol mix gas in it that they added startron to. The top one inch of 20oz bottle is pure water the startron pulled out

 

The advantage of using premium! Shell doesnt use ethanol in premium fuel and possibly others as well. I used to work on fuel tankers and attest to how brutal ethanol is. Emissions standards will be the death of the modern engine and the ability to repair cars yourself.

 

I wish they would do that here.
