ok took the head not off but apart on the motor to make sure it wasnt anything messed up n clean everything so i did that n put everything back together n put it back on timing n still nothing plzz need feed back.........

canadaek

so in 15min you took the head off cleaned everything and put it back together? You know it takes a much larger volume of fuel to rin e85 right?

running from gas to e85, should be tuned for the differenct in gas used, otherwise it isn't going to run right and may cause engine failure

jokereg4lyfe

No I didnt do that in 15mins I had already done it just forgot to add it

I was wit the tunner when we which the gas n I used his map that he had done right there n than but tge car is running like crap no one knws wat it can b

Fliptard

if both motor set ups arn't the EXACT same, the map won't work properly with yours.

If the engine is mechanically clean and timing and all is spot on then you have problems with ECU or electrical. Any codes?.. well, your tuner would have noticed a CEL.

Sounds a bit like pre-ignition, where the mixture is combusting too soon during the compression cycle. It will cause the cylinder to heat up even more, like a downward spiral that robs power when you want it.

Then again, you might have ruined the O2 sensor running that E85 through there.

my tuner by passed the o2 sensor so its not that. and everything else looks gd i would like to get this fixed asap plz so if u have any feed back that would help wit this plz post thanks..............
