i have a 2001 f4i. just bought it bc it didnt run and dumped fuel out the exhaust when it was turned over to try and start..i pulled the injectors sent them off and had them cleaned....put it all back together and started it....started perfect except that it dumps gas out the exhaust very bad like....so i pulled the throttle bodies off and tried to start is injectors 1 and 4 are spraying perfect but 2 and 3 arent spraying they are like pouring i guess you could say.......please help all info i valued

 

well, if you narrowed it down to bad injectors (which you did) then your next step is to get new injectors.....

 

i sent them off to get cleaned...they take before and after pics....there is nothing wrong with the injectors

 

Did they just clean them? Or did they clean and flow test. Is gas pouring out fast? Or pouring out like a hose at about half strength?

 

ok.. so move the 'bad' injectors to the cylinders of the 'good' injectors.. if it does the same thing in the good cylinders, the injectors are the problem...

if the problem remains in those cylinders... the problem is not the injectors...

rule things out quickly.. and cheaply..

I did do that. I sawpped 1 and4 with 2and3 and it remained in the same cylamders so it's not the injectors. And Ted they flow tested them. 3 out of the 4 injectors made only a 3.5% flow increase
