Hey guys I have a glanza v with all the usual mods hybrid pnp n rad ect. But when it's on idle it ticks over lovely but occasionally it sounds like a little his noise comes out n the idle drops I was playing around the other day fitting oil catch can and I started it wriggled this wire n the car cut out?? Basically when your looking at the engine bay there's a little solonoid looking thing on the firewall drives side called turbo reg. it has 3 wires coming from the plug and if a wriggle them it makes that his noise then cuts out? Anyone heard of this before?? The wires go into the casing that runs over the injectors down into a maze of wires?
