Check Engine Light

Check Engine Light
OK - this one has been going on for over a year - when cold a little rough idle, engine knock and hesitation. As it runs - get some dieing at stops, hesitation on acceleration - on a long run - couple of hours on an interstate it gets real weird - all the idiot lights and gauges flash on and off usually starts with the Transmission and airbag light then a few minutes later all lights and gauges start flashingon/off- runs rough hesitates, stalls, etc. Most of the time no codes. Next morning may get nothing or sometimes a check engine light - runs fine - for awhile
Oddly usually runs a little better in manual mode once the trouble starts. Maybe a transmission problem masquerading as an engine issue?
When codes do pop up it's a range at different times these have shown up P1316, P0301, P13113, P305 & P1314
Too date - five shop visits
New MAF
New coils - all
New plugs and wires
New (used) knock sensor
New catalytic converter
Dry gas 4 times
130K and has been well maintained - my wife's baby and she has had it since new.
I only run premium and try to buy at 'name" stations.
Ignoring the codes I'm going to replace the fuel filter this weekend.
Any ideas would be appreciated - two Jag specialist shops have both struggled with it - one in VA and one in TX - they are as frustrated as I am. Love the car but told my wife to start thinking buying a new one.

My research has found:
P1316 Injector Cir / IDM codes detected
P0301 Cylinder 1 One Misfire Detected
P1313 Misfire Rate Catalyst Damage Fault - Bank 1
P0305 Cylinder 5 One Misfire Detected
P1314Misfire Rate Catalyst Damage Fault - Bank 2
I would chech fuel injectors and spark plugs and spark plug gaps

For those kind of symptoms I'd be looking for an HT electrical leakage. Although you have replaced the coils I would still be looking in that area. Were they brand new coils?
You haven't said what car/engine/year this is - that would help.
Assuming it is an X300 with AJ16 engine I'm confused by you replacing the plug wires?
