So, I know I need to get the Opti ignition rebuilt, there's a slight miss in the engine. But I have this weird tapping noise that sounds like the engine tapping, but only when I try to parallel park the car. Does anyone know, is that the strain on the engine from the Opti not working right at very low RPM's when trying to use the power steering pump to park causing the engine itself to have a loud knock? Or could this tap be something else, like the PS pump maybe? I never heard/felt anything quite like it. At 35-60 when on the road, the engine does not sound or feel too bad, maybe a slight miss. Definitely a miss at slow speed. I'm using the car right now only as a backup, and sadly money is pretty tight right now, that's why the Opti is not rebuilt yet.
