oil pressure jumpy needle

[Red Rover]

I just had the diesel injectors replaced on my '81 300CD the other day. When I was driving today I noticed when coming to a stop the oil pressure needle drops to an acceptable range 1.2 bars .... but when I put the car in park the needle jumps up over 2 bars, more like 2.4 bars. This has never happened before and was looking for advise here.
Thanks guys!
side note: I need to replace the drivers side turn bulb up front ... how do I get to it??

Look behind the turn signal lens for a white knob and unscrew it. The lens assembly should slide out and you can access the bulb.

Nothing unusual. Your idle speed increases when you change from 'drive' to 'park', which increases the oil pressure.

I actually turned the "key" behind the steering wheel down a notch to lower the idle and now it's running like a "german" clock.
I replaced the turn signal bulb but the alignment on the lens cover is still off a bit and have been playing with it to get it straight.
