I have a 2001 S-type 3.0. It was originally the one with error codeas 1383 and 1388, they came up randomly and would go away and come back. After having a mechanice replace igniton parts and inspect the solenoids i still continued to have the problems. I bought the card used and it looks as if the wiring had been spliced to the coils and solenoids, I had the mechanic inspect it and solder it on the drivers side bank (atleast to the solenoid) and the codes still came back... (one seemed to go away, i think 1388).

Then one day I'm driving home, decide to pass a car on the interstate... was doin about 90 and slowed to about 75, then my car did what I call 2 or 3 "surges", just tiny fluxuations in rpm/speed (very tiny, almost the reverse of two tiny revs), then my car came back and acted fine, i sped up, slowed down and fine... I continued to drive about 5 more miles, got off at an exit and heard a car knocking when I got down to about 35 mph, I realized it was my car near the next stop sign, i then stopped at the stoplight and my oil pressure light came on, It sounded pretty back, loud knocking, I drove to my house ( 1 block away) and parked. I talked to my mechanic he said sounded like I need a new engine. I feel like there was probably an oil supply failure at somepoint (maybe gradual solenoid fail? and then oil starved engine?) my car started when I tried it again. It has only the same error codes ( i think only 1383), I checked the oil level was fine looks fine (had been changed 1000 miles ago w penzoil (first time i used i think, 5w-30), I have looked at the drivers side bank, it looked ok, some oil in one of the spark plug seats, checked that solenoid, just had a tiny bit of metal flakes in the screen--(heard this can be solenoid itself).... That is as far as I've gotten, next is to take off other bank, I'm praying to see a very clogged solenoid screen... and not a completely destroyed head. IS there anything I should look for/ SUGGESTIONS PLEASE!!!/ When I checked the codes they say possible VVT actuator stuck, solenoid fail, valve fail.... etc...
I'm trying to decide whether to keep and fix or sell and cut my loses, WHAT A MESS, PLEASE HELP!
