I got a d16 turbo w/ a walbro intank.... the car was driving fine for over a week, but now it leans out at full throttle over 5 grand....
I put bigger prelude injectors, but still no luck.....
i tried a serch, but didn't find anything helpfull....
so please help me out....

 

Is your fuel pressure dropping? You might be loosing your fuel pump. Blip the throttle and watch the fuel pressure if you have a guage and see if it drops. If so its your fuel pump

 

I just put it in bout two weeks ago...
should it go bad so fast????
thanx though

 

what is your complete setup?

 

It should not go bad that quickly but I went through 2 brand new holly pumps in 3 days because of bad fuel management. Too much fuel pressure in the lines. You really should list your complete setup so we can help you out better

 

I have an f-max kit with an FMU from a sohc turbo kit...
I put in a walbro 255 intank pump...
It was running great like that... the only prob. I had was a slipping clutch...
Then a week later it starts to lean out after 5 grand....
so i installed prelude injectors w/resistor pack.. to get more fuel, but still no luck....
hope this helps...
thanx again for any help....
later........Z

 

help

 

If you have checked what I told you then my only suggestion is dyno time. You can't go wrong with a wide band O2.

 

cool thanks...Z

 

so you have a 12:1 fmu w/ prelude 310cc injectors and a 255lph intank or inline fuel pump? What's your fuel pressure look like?

 

i have a intank, but havent actually checked my fuel pressure...
first thing monday morning...
but if it was the fuel pressure wouldn't it have never run right???
