I had a problem recently with my RS hesitating whenever it got to around 4500rpm in any gear. I read this could've been caused by the fuel filter/pump so I replaced them both. Installed a Walbro 255 and found that the car previously had a DW200 in it. The car started again fine after the new filter and pump but I didn't drive it. Got in it last night and the problem has gotten much worse, the car will bog down just as boost is about to come on and it feels like a fuel/boost cut. The engine wont stall but will struggle for 3 seconds then will continue running. Keeping the car under 2000rpm it seems to bog down randomly without anything happening.

 

I'm getting a list of stuff to look at tonight and was wondering if anyone can add to it.

- Swapping out the maf for another

- ECU reset

- Check plugs

- Different cam shaft sensor

What coil packs are you running?

It's got a Bosch coils upgrade, I have some original ones I could try  

[Reevesy]

Try the original ones (make sure the have no cracks in them)
And bkr6e plugs gapped to .7

And a MAF clean/swap

Replaced Maf, coils and plugs. Everything was fixed so went for a drive and it went well. Stopped then headed back and it's all back to the problems again. Will be changing cam sensor and revert back to the original pump fuel filter in the morning.

new pump doesn't have a higher pickup point by any chance, does it?

That may have been the problem, put the old one on and cleaned the o2 sensor up and the car came good again
