So i got injectors from a 95 camaro for my 93, they worked well in there so i figured id have no problems with them. I got a chip from ion, and put them in. now, when i start the car, the idle will drop and raise randomly, the car will miss, and i have a crazy sucking sound coming from my intake. sounds like a vaccume cleaner. its really loud. this stuff only happens when i first start the car up though. once it gets warm it runs perfect. any guesses on what this could be? thanks -dave
