Henny 0 Posted November 12, 2003 The MPG is fed via a vacuum hose from the engine bay... If this falls off then you'll get mad readings like 99.9... It may also affect the engine's running as well as you'll have a vacuum leak in the system somewhere... :? It's also worth checking all of the ends of the vacuum hoses (thin plastic tubes) as they have a braided rubber connecting pipe on them which sometimes goes porus and so lets the vacuum leak... :roll: Quote Share this post Link to post Share on other sites

chrishill 0 Posted November 19, 2003 I've got the same problem on my 16v, seems a bit lumpy to start sometimes and quite frequently shows 99.9 for the MPG, so i'd find a picture of the pipe useful too! Quote Share this post Link to post Share on other sites

jimbo-corrado 0 Posted November 19, 2003 The vacume pipe on mine goes to the back of the dash ( speedo clocks ) , i think this is the sensor , when the car is at idle can you hear an air leak from behind the dash ? if so the pipe may have come off . im not sure where the other end goes to , somewhere on the inlet side so have a listen for any air leaks at the back of the engine .
