2002 E53 Fuel Injector connector removal issues

[harleyclassic2]

The electrical connector on the Fuel Injector seems to be stuck ...the retaining clip on the connector is released but the damn connector just does not pull off. Its the 1st one closest to the passenger compartment with very little room to maneuver. The rest of them are out. The fuel injector itself seems to rotate now.

I can try to release the whole fuel injector itself...but would gas leak out ? ( and don't want additional problems)
Any ideas on removal ? Maybe an O ring is stuck ?
Anyone had this problem ? (hope this description is clear)

Thanks

CN90,Thanks for the tip --it came off after some Carb spray.

Would you happen to know - or point to - torque spec on cylinder head cover fastners ?

I use a paint can opener to get the clips back hooked on - especially the 2 rear ones.
Ridiculous Clip system to hold the connectors on.

I got those hook tip screw drivers for a dollar from harbor freight . ..but f#*# up putting back 3 n 4 th connectors back. I think.
The code I get now and the car chugs is

0098
EV 3 from Cylinder 4

009B
EV 6 from Cylinder 3
(both passenger side where I did the gasket)

This code is from a diagnosis program but does not explain further.
ANYBODY KNOW WHATS UP HERE ??
THANKS
