I have a 96 na-t with aem version2. Well here is the problem. the car drives perfectly when driving around. but when i am about 75-100% throttle and around 5500-6000 rpms it hits like a boost cut. but here is the kicker. the car completely shuts off. i have to actually pull the key out and put back in before the car will restart. it wont even let me dump the clutch to restart it. spark plugs are gaped right around 23. hit the vacuum lines with carb cleaner. no adjustment in the rpms. suggestions?
