Hey guys, just recently, have noticed that my car has no torque at all within rev ranges, It hasn't been tuned I know but thus can't be the issue. Cause it was still very punchy even without a tune. I compared a rolling start against my mates XT forester first time and it pulled away no problem, but today i compared again and he was reeling me in so I knew theres a problem there, I'm worried as its coming close to my SKR tune in SA and I want to have the car ready to go for then. I also had just got a 75 fitted so thats excluded from the issue. Now here's the situation:
Driving along say at 60kmh, and decide to depress the accelerator pedal all the way down, in 2nd or 3rd aswell, from 3-5000rpm it slugs along and feels like theres something restricting it, anywhere before pretty much 3-3500rpm it picks up nicely and there onwards, depending on how much you accelerate, it slugs.
Cause if I do the same acceleration procedure but only using 50-75% on acceleration, it has no problem to accelerate smoothly and picks up nicely, but any harder down on the pedal, it slugs.
I've checked air filter and that seems fine. Checked transmission oil just incase, that seems fine. I also noticed a rattling noise coming from the tank I assumed. I pulled out the pump to have a look, it all seems to be fine, nothing was loose at all, but did notice one thing, is that once the cars started, running, idling and even moving the fuel pump noise isn't a constant smooth buzzing noise, its more of a sound like you'd hear an SOS message and can still hear the rattle. Could it possibly mean the fuel pumps on its way out? And is it best of replacing both filter and pump since they haven't been replaced since I have owned the car?
If so whats a price on a new fuel filter and fuel pump? Genuine preferably, as I will replace them both myself.
Cheers guys.
