Feel like I’m starting to bang my head against the wall this surging I keep getting when I put my fl1 td4 2004 under hard load image is showing the blue line is the inlet manifold pressure as you can see it’s up and down like a yoyo only does it if I accelerate harder than usual but if steady acceleration it seems fine and pulls ok any help or ideas would be greatly appreciated before I burn the bloody thing
