Injector connection? Make sure you mentally note the precise thing you did that "fixed it", cause it ain't fixed until you clean that connection thoroughly. If you can't find a ground from a valve cover bolt to the radiator support, MAKE ONE. You can't have too many grounds. My 84 CRX had a bad ground when it was built. Right radio speaker open circuit, factory new wiring harness. I just added a ground.

Also no need to garden hose the engine, a spray bottle like windex is fine. You could damage the engine if done completely wrong.
