Hi chaps after abit of help I’ve run out of things to try and I’m at my wits end 😂 so ill keep it short. my issue is hunting at idle and will sometimes stall , boost gauge also goes into negative when it’s hunting, I’ve replaced the manifold, all lines vac etc, pcv, idle control valve and MAF sensor, still the issue persists, today I cleaned the fuel pump filter in the tank it was pretty blocked to be fair, still the same, was told it’s a walboro 255 fuel pump but I’m not sure if anyone can confirm from piccy ? also tuck plugs out and they are black not wet but black and they where brand new. Maybe my issue is fuel related I’ve done some research and my regulator reads nearly 3 bar on tickover with vac line connected, this seems high to me ? anyway I’ve gone on abit if anyone’s got any advice pointers etc please let me know regards Lee
