Hello fellas,

Seems if I have another issue the last couple days.

Started 3 days ago on the interstate on the way to work. Was cruising in 5th gear when all of a sudden the car sputters out. Every time I pushed the gas pedal it would not want to go anywhere.
I then pulled over, turned car off and sat for a few

Started it back up and was good. Then a few minutes later the same thing happened

Then as soon as I got off interstate it stopped

Then yesterday the same thing happened. For a second I though I ran out of gas the way it was sputtering.
Seems weird that it seems to only happen on the interstate.
Any input? Bad pump or fuel filter?

2.8, 80's, e85, flash tune
Been on e85 for 5-6 months

 

No codes? That almost sounds like reduced power mode, makes the car sputter and not respond to throttle input.

When did you last change the filter? If it's been more than a year or you don't remember, change it anyway. Then log your fuel trims on the highway, if they start going way positive before this happens, then yes you have a fuel supply issue.

Or you could change the pump anyway, the housings are starting to fail on the earlier cars by this age and due to your future fuel supply needs it wouldn't be a bad idea to upgrade to a larger pump at the same time.

 

What would cause the engine power reduce? No codes

I have never changed the pump or filter and has almost 100,000 miles on her

 

change the filter

 

I would take joes advice and replace the pump and filter and also run some lucas e85 fuel inj cleaner

 

i'd say check your pressure first it should be in the 60 (i think?) psi range at idle and stay there while driving and in boost but either way your filter could be replaced, especially now that youre on E

 

Ill replace the filter tomorrow

Whats a good aftermarket pump? Wabro 255?

 

you don't need an aftermarket pump with that setup. It sounds to me like your throttle body is going bad but without a code being thrown its hard to say.

 

Thats what I thought at first also was the TB
