Hey guys, my 2002 Camaro pulled a P102 code, changed mass air flow sensor. Previously even after sitting for a couple weeks I could go out put key in and start right up first time. Now I start and before I can get into forward or reverse engine dies. After it dies, I have to start and rev engine then it dies, I start and rev engine then it idles. My husband says this isnt possible cause of the fuel injection system. Anyone any ideas. Prior to mass air flow sensor problem, basically did a 100,000 service at home on vehicle, changed plugs, wires, all fluids etc. When I get it to idle it is ready to take off and runs like its screamin but the dying after starting is confusing
