Ethanol causes problems?
SO I recently moved to another state (Arkansas). Since being here, my truck has been running like crap.. stalling, poor idle, sometimes hard to start.... almost like it doesn't get enough "boom" to "fire" it up.
Supercharger 7.5 PSI
So I have been deducting the possible causes. I already replaced the throttle positioning sensor.. no help.
So I deducted what has actually changed in the last month.
1. The air has gotten warmer. I know my truck is running rich and I thought maybe since the air contains less oxygen, it may be running too rich to run good. (Getting new dyno tune tommorow)
2. Gas change. While filling up today, I got about 1 gallon into the fill-up and noticed "Up to 15% ethanol". WTF?!?
I know that most of the gas in the nation contains 5-10% ethanol.. but up to 15?
My question is... could this be what is causing my problems?
I left there and scavenged the county for a place that sells 93 octane and doesn't mention ethanol. I found a place and filled up. I drove about 15 miles to fully mix the small ammount of "ethanol gas" with the new gas.
It "seems" to idle better.... It could be in my head.
COuld the ethanol gas be causing the problems? Anyoneelse have a similar situation?
