so have had code 3 pop up for the past few days when the car goes into boost. what is happening is it good up till 7-8 lbs after engine light comes on. no vacum leak checked all and the only thing i can think is map but like i said its ok up till 7-8 lbs off boost. also temp gauge is all wacked out here lately when car goes to boost or even just pick up like normal drv cond. the gauge goes up and dwn but never passes 1/4 the way up past norm drv cond.any help would be great. thanks
