ScORTED Posted May 28, 2005 Share Posted May 28, 2005 sensors are such a pain in the knackers... get a garage to do a diagnostic if you suspect a faulty sensor, its better than changing em all! Link to comment Share on other sites More sharing options...
Matthew H Posted May 28, 2005 Share Posted May 28, 2005 also check there is no air leak in the induction system Link to comment Share on other sites More sharing options...
p3boy Posted May 28, 2005 Author Share Posted May 28, 2005 taa people, i will try the suguested above sorry for sounding stoopid but MAF is the mass air flow meter/sensor thingy aint it? I work for vauxhall and to me they are just air flow meters! Link to comment Share on other sites More sharing options...
