Hi All,
Ive got an Series 2 2003 VY SS(auto) that has had a harrop HH112 Supercharger fitted. All work was carried out by the Horsepower Factory. Recently the vehicle has devoloped a miss under load between Idle to 1700rpm on occasions. I can drive the car for a week or 2 then outta nowhere it devolpes a miss which can cause the car to stall and it seems to arise after ive taken it for a drive and then start it up again. The miss will disappear if i apply the accelerator a tiny bit more and will rev out fine.
Ive had the car on a scan tool and the only fault code that comes up is the maf(but the maf was switched off during the last tune) Ive replaced plugs and leads and the o2 sensors are working correctly. Any ideas???
Also there is no engine light that comes on and the PCV+lines to and from it are not leaking/cracked
