Hi guys, We're running out of ideas with this problem on the Glanza. Sometimes the car runs absolutely perfect, then the next day it idles funny. Now the car runs lumpy, as in the revs go up and down from 1500-200rpm while the car idles. The first thing we suspected was an air leak after the throttle body so we checked that by blocking the throttle body and the car cut out straight away, so that rules the air leak out. We tried the usuals such as adjusting the distributor and TPS but nothing helped. We removed all the vacuums that feed the boost gauge, boost controller etc and looped the manifold on itself but this didn't make any difference either. We then removed the vacuum to the MAP sensor and the idle went smooth and dropped down to around 1100. So, we tried another MAP sensor but that made no difference either. We've checked the spark, fuel etc and there's nothing suspicious to be seen. Any ideas would be appreciated? Cheers Idrees
