Hi guys, i have a 94 wrx 2.0 turbo. the vac lines seem pretty good and the car normally runs pretty well however whenever the heater gets turned on it starts surging once it gets to operating temperature and as soon as i take my foot off the accelerator the car stalls. if i turn the heater off then start it up she runs fine again. Can anybody please help me im stumped! :confused:
