I eventually got code p0030 which was for an o2 sensor, so I switched back to stock tune and took it to the dealer after the light came back on even on 93 octane. Got that sensor replaced but then on the drive back home after replacement it did the same thing and stumbled and turned off at a redlight after a spirited drive. Code hasnt come back on yet but its doing it even on 93 octane stock tune for me now.
Well that sucks Mine hasn’t thrown a code yet. I’ve been on E pretty much since I bought car new. 3700 miles on it now. Just filled with 93 on flex tune so we’ll see.
I have never tested that specific product, but I have tested other stuff from Lucas in the past. We often had issues proving that their products were actually doing much, but that was long ago. They may have stepped things up in the last 7-8 years. The product mentions corrosion inhibitors, which you really don't want in an additive. Ethanol fuel is loaded with corrosion inhibitors, and that directly increases intake valve deposits. Personally, I run straight detergent. There isn't anything else you need.
Well my tuner and I tried bumping the idle up and that did not work. Back to stock. It did die one time on way back home. Going to drive it 20-30 miles on this 93 and get it into Ford. No lights nor codes...?
Same here. Been on corn for almost 5k miles. It appears that Andy, you, and me have a similiar problem. Wonder if it might be the throttle body acting up at idle?
I am at around 3k on E85. Still no issues, other than some hard starts when the weather was cold. It will be interesting to see if I have similar problems in the next 2k miles. I haven't even run the occasional 93 oct tank that others have.
Yeah I’m back to stock as of yesterday. Want to run a couple tanks of 93 top tier through it. Skipping the additives. Less is probably more in finding out what the hell is up? Crazy this is happening to e85 tuned cars though. Different tuners too.
Could happen. EtOH is generally well regulated now, but they can't do much to control it once it leaves the terminal.
True, and I think we still have some winter blend sitting at the pumps. Crazy the car ran normal with some slight surging for 7 mos without stalling @ idle on E85. All of a sudden Feb it starts. Zero dtc or engine lights?
