I just installed my used 30# injectors and new pmas air meter and now the car runs like its on 7 cylinders. so I put my pro m mas air back on and the car runs smooth as long as your giving it a little gas, it will die if you don't ,but it's calibrated for 24# injectors. At first I thought one of the injectors didn't work, but they work fine with the pro-m . has anybody have any problems with the pmas meters?
