vvtli 190 celica 2002.I have a problem when the engine gets warm, when I bring the car down to tick over,it revs at 1500 and blips the throttle to 2000,on off, like someone revving it for you, it then will suddenly change, drop down to 900 and runs sweet, few minutes later it's at 1500 again revving to 2000, could this be a problem with the coolant temperature sensor, iacv? Maf? Can't find. Any vacuum leaks as such, please give me your knowledge. Thanks,j :-)
