I have a KJ Cherokee that has developed a missing problem
I took it to one place that charged me 10 hrs labour and was unable to pinpoint the problem.
I decided to take it to a Jeep dealer who after 3 hrs have found it to be the
ECU male connector ....albeit 80% certain
They are saying it is a 3 hr job plus 6 weeks to get the connector from the USA.
What they said its doing is cutting out the injector to one cylinder.
These codes are coming up:

P0340
P1391

Does this sound like its the likely problem ?
And is a dodgy male connector likely to keep making the same codes come back?
Where can I get the male connector for the ECU? Anyone have any suggestions ?

Cheers
