Review on ACDelco 217 3021 Original Equipment Multi Port by Reid Rickerson

I knew there was a bad injector but there was no way I was going to take it apart for just one. Works great, I'm sure a few others were weak too. Works better than I expected after installing it. It's a hassle to get there, replace the plugs if you removed the top air intake and glue the air intake gasket onto the top air intake or you'll never be able to install it without damaging the gasket - if you don't have one The firewall engine makes this a difficult task.
