I just hooked my Foxwell NT530 into the OBD port to discover two generic codes:
P1341 (inlet camshaft bank 1) and
P0430 (Cat. converter efficiency, bank 2) had come back after clearing some time ago.
I'm asking about these codes after extensive search because I was curious what others think: The
P1341 code came about after I had the IMS replaced with the IMS Solution almost 2 years ago. I had the shop that did the work take a look with their durametric to see if there were any cam deviations, they said they looked to be in spec (I didnt get a readout, in hindsight should've). The
P0430 code came after I did the plug/coils and didn't seat the connector on cylinder 5 coil pack (or 6, cant recall) and got a massive misfire/flashing CEL. Flat bedded car home, reseated the connector, all has been good.
My question is what might cause these two cleared codes to come back? My initial thought is I should be looking at the bank 1 Variocam Plus solenoid, checking oil for green or brown bits (its due for an oil change). The bank 2 car efficiency is more confusing as it hasnt misfired at all.
I've read about codes that are:
And it would seem these have to be stale... yet they're back.
Car seems to drive normal, tho my b*tt dyno tells me there's a slight fall off of power at higher RPM - but that might just be normal too. Idle after warm up is varies in a range of +/- 50 RPM from about 670-700 rpm or so. Startup there's no chain rattle just some clatter I would think are injectors. At 3000+ RPM in 6th gear there is some driveline vibration (engine mount changed 1000 miles ago, greatly reduced this) that I think could be trans mounts going out. No real hesitation or stumbles otherwise.
I was thinking of going back to an indy to check out cam deviations and have them do an oil change looking for brown/green bits (or do that myself). I was also considering spending $280 for a bank 1 variocam plus solenoid as well. Just don't really know best way to proceed.
