hey guys, i have a v6 vu ute 5 speed manual and my friend has a v6 vx sedan which is also a 5 speed manual. to get to the point in both of our cars when you change gears the revs seem to go up about 200-500rpm (yes 200rpm not 2000rpm) or sometimes when you change gears say you get to 3 grand take my foot off the accelarator, clutch in it will sit on 3 grand for a second before the revs drop down. i have read that maybe it is the iac sensore so we have bought new iac sensors and both iac sensors were too small they just came apart in the throttle body which was weird, but we have tested the original iac's and they are working fine they move in and out with no problems which leads me to belive that it isnt the iac, also we tried replacing the throttle position sensor that has also not fixed this and also have checked that the throttle isnt sticking have lubed up the cables and it only does this when im changing gears. is anyone else experincing this and is it something that can be fixed i have google searched heaps and all i seem to get is maybe its the iac sensore or that when the clutch pedal is depressed it touches a switch that tells the ECU to increase the revs to make the ger changes smoother. i dont think this the case though. has anyone excperienced or experiencing this problem? any light shed appon this problem would be greatly apprecited. thanks guys.
