any feedback would be helpful
cheers

Most likely you have a vacuum leak in your charge-air system ... the intercooler+piping needs to be completely sealed due to the way the oem maf works. Usually a clamped intercooler hose has simply popped off...loosen the clamp, put the hose back on, and tighten the clamp. Note that sometimes the place the hose has separated is in a hard-to-access/hard-to-find location.
