I have a 1994 GT The motor is a 306 with GT40 Heads, Lower intake off a 96 Explorer and a cobra upper.. I am running 19 lbs injectors stock MAF and throttle body. I am pretty sure the car is running a E spec cam but i have no way of verify that.. I have replaced the TPS, and cleaned both the MAF and IAC. The car runs a little rich, and according to shop i have it in, the VAC drops to 14 PSI when at idle.. The readings we got were  HC ppm LImit 200 Reading 357CO%      Limit  1.00 Reading 1.3Other then a idle surge when she is cold started, the car runs great, has plenty of power.. The shop which is a drive clean repair centre believes it's my cam that is giving us the issues.. I am not to sure.. I believe that.. I really need some help here guys, This is my last temp sticker for the year.. I need this car for school.. IT HAS TO PASS and soon!. ThanksDon</blockquote>
