Is this ping a recent event? Check over all vacuum, pcv, egr systems to make sure all is well. That connector your're talking about is probably the spout connector, it's used to check base timing on the car. Do not run the car as a matter of course with this spout disconnected, 4 degrees retarded is too much, may overheat the engine. Even cars where the timing could be adjusted, my 94 Taurus, factory says no more then +or- 3 degrees, but without some major issue such as carbon buildup on the pistons, in the intake manifolds, or in the egr system, you shouldn't have to fudge the timing to make it go. Do a compression test, see what psi you're getting. After you've done a thorough check of all the above, also make sure your air intake system is intact.
