Flex fuel numbers keep jumping around

[Ronny2019]

Well i fixed the issue. I was having my e#'s go crazy sometimes starting my car in the mornings they would be reading about 60-70 percent but really only had like 30-35 percent. It would slowley go back down but stay a little high and jump around by like 10-15 percent. But i read somewhere on this form to use dielectric grease on the plugs to my flex kit and it totally worked the numbers went down to the real amount of 22 percent from 27 after using the grease and have not had a problem since. Just wanted to post this for anyone who has this same issue. Hope it helps someone as it did me

This happened to me before. My STFT were all over the place cause the ETH% kept jumping around in big numbers, turned out to be a loose ground connection on the flex fuel kit

I wrapped a huge section of electrical tape around the single wire on the prl kit right before the plug and made sure it seated into the plug with the wire ending. Have had 0 issues and definitely driven through enough rain and water make sure. The E content does fluctuate by 1% though if you end up with a mixture that is not exact, drives me nuts.

If you're fluctuating at 1% you're likely at +0.5% of the lower number. Nothing to worry about.
