CLEANED BOOST SOLENOID

Had a bit of slight hesitation at just about 2000-3500rpm while just holding the accelerator slightly. Would drive through boost fine, but it was annoying me even in 5th gear at 3000rpm it would slightly hesitate. So took off the hoses from boost solenoid and sprayed carb cleaner into the holes of boost solenoid, was a bit of dirt came out, put hoses back on and started it then took it off again sprayed it again and then put it back together. They no hesitation anymore boost change over feels a lot more reponsive and a lot better feel to accelarator response it pulls better to. Amazing what a bit of carb cleaner can do!!!!!!!!!!!!!

Also good to check the gaps in the plugs and coilpacks for little cracks inside the bit thats goes onto the plug and the face of it

Yes thats it theirs 2 pipes going into it take them off connect the connectors together you will hear the relays clicking and fans but it normal the boost solenoid will click and just spray the carb cleaner in the holes and you see the crap come out
