I need help,i usually go through 3 MAF Sensors a year, however over the last year i have been replacing now every 4 to 6 weeks and at £120 a time. Codes are MAF and speedo sensor, the speedo has started to come and go and every time the speedo goes "check engine" light comes on, press clutch and let revs go to idle and warning goes off, had this for a bout a week then the MAF Sensor goes. I have replaced the last 2 every 4 weeks.
The car is a WRC555 TYPE RA LIMITED 1998, it has been re-mapped by AF. It only runs on tesco momentum 99 and if i put different fuel in the maf goes (i know that so always 99 now)
Something is sensitively wrong, any help or advice is most welcome,
Many thanks
Paul
