[corofin12345]

yes it has been timed

[somal]

well the only things i can think of are plugs, filter and timing.. is this only happening lately???

 

[ktl]

maybe the ecu ?

 

[Gtstu]

Whats the fuel pressure set to?

 

[somal]

the fuel pressure is set to 42psi, i had a mines ecu before and it was the samething, excess fuel

 

[ep82 starlet gt]

thats over 3 bar isnt it...... thought u only had to run that kind of psi if ure boost was around 1 bar.......

 

[somal]

i am trying to seek help here from u guys, so all input is welcomed...would it be safe if i just adjust the fuel pressure just like that ?

 

[ep82 starlet gt]

crank the pressure down a bit. either that or turn up the boost.

what ecu do you have running on the car at the minuite?

 

[somal]

i have the chipped ecu on atm

 

[somal]

Could it be spark plugs, leads ? fuel pump ?

 

[corofin12345]

Could it be spark plugs, leads ? fuel pump ?

no harm checking the plugs and seeing are all the gaps right

 

[somal]

been having this problem for months, what KM should i have been getting from a full tank of gas ?

 

[tommy]

could be your lambda sensor either

Could it be a fuel leak? Had the same problem and discovered fuel leak at the fuel return pipe under the car.
