Do you guys think my wideband sensor got moisture in it from sitting all winter and is reading lean? Or my injectors got dirty enough for the car to sound like it has rotational idle whenever my car is cold and I blip the throttle, I have 1300 cc blox injectors and run e85 and a Bosch wideband I replaced last summer

 

Welcome to the wonderful world of E85. You cannot let a car fueled by E85 sit for long periods of time. Alcohol/Ethanol damages everything.

 

If youre in a humid environment you have to flush the e85 out.

Im in socal and have never had an issue letting e85 sit in my tank.

 

I've never had a problem letting e85 sit for long periods of time either. I think 2-3 years might be the longest I've had an e85 car sit, but it was still OK. I've also never had e85 ruin any OEM lines, seals, filters, or components. Or aftermarket stuff for that matter
