  1. Well, I'm back. After driving fine for a few days, the car started idling rough again today. I pulled the code, assuming it was probably P1354 again. However, that is NOT one of the codes this time - now it's P0300, P0302, P0304 and P0306. I will have to check my paperwork, but I believe I had the corresponding ignition coil replaced less than 3 years ago. Anyone have any recos? Seems weird that this happened right after P1354 and was hoping for advance before I go on a wild goose chase. Thanks!
  2. Update: the CEL came back on Thanksgiving and the car starting running rough again, this time not just at idle. Was able to pull a code this time - P1354. After plenty of Googling, I pulled out the OCV closer to the front of the engine, cleaned it with some brake cleaner and reinstalled. Took it for a short test drive, and *fingers crossed* it seems to have remedied my issue. Will circle back if I have any more issues. For anyone else that may encounter the same issue, these two videos were helpful for me:
  3. Apologies for not including mileage - just under 154k at this time.
  4. Hi all, I've had an intermittent check engine light illuminate over the last few weeks. When it comes on, the car experiences a very rough idle but seems okay at driving speeds. I originally suspected it may be due to the fact that my battery terminal connectors have been coming loose and the connection was spotty at times, however, I have rectified that situation and still have had the CEL and rough idle return a couple of times since. It seems to most often occur after I've already driven (not necessarily a long distance) and have stopped somewhere and gone to head out to somewhere else. Two occurrences ago, I parked and popped the hood after the light came on to adjust the battery connections and it looked like the (pardon if I use the wrong terminology) pipe coming off the exhaust manifold was glowing red. It only happened that time, no others, but it was after maybe driving 10 min one way, stopping for 5 min, and driving for another 15 min - so not long enough I'd imagine anything would be glowing. I've included a pic of what had been glowing red (note, it is not glowing in the pic). I tried to pull the code with an OBD2 scanner. The version I had was asking which interface to access and I chose ISOsomething. I can't recall which, however. At this time there is no CEL and the scanner did not retrieve a code. I thought codes were stored as long as they were not cleared, so I am not quite sure why it's not returning anything. Anyone have any ideas? Should I be concerned at this point as long as it happens intermittently? It's a VERY rough idle and the CEL is blinking, which to my understanding is worse than a solid CEL. Not sure if I could've picked the wrong reading option on the OBD2 scanner - it's an Ancel AD410 if that's any help. I may be driving my car across Colorado and Kansas next month over the holidays and am wondering if this issue needs to be addressed or perhaps is a ghost in the machine. Appreciate any advice!
  5. Thanks for the information! It seems most other people that get the P0325 code also get P0330... which I didn't get. I hope that's a good thing. There has been a new development - I drove to work today and also ran to get some lunch. On my lunch run, the CEL disappeared. Over the weekend it was pretty rainy here, and today it was very hot. Is there any chance the CEL could've been tripped by the massive amounts of water I had been driving through (and cleared now that the car has dried out)?
  6. Hi all, I became the proud owner of a 1999 ES300 about 8 months ago. She's got ~82k miles right now and seems to run smooth for the most part. A couple of days ago the CEL came on (along with the trac off light, which from what I've read is standard when a CEL is thrown) - I borrowed my brother's OBDII scanner and found that the CEL code is P0325. Given that the code is knock related, I was hoping a new tank of gas from a different station may solve the problem - but after clearing the code and driving about 50 miles, the light (and the same code) came back. Being new to the Lexus realm, I wanted to inquire and see what the possible causes of the code could be - most obvious being a bad knock sensor... but with my previous cars, there were always other possible problems to throw a CEL that may not fit the code exact. Any input, etc would be greatly appreciated! If it is a bad knock sensor, how difficult is it to replace for a DIYer? I'm no mechanic, but I can be pretty handy with a wrench when required (I've replaced turbos, clutches and timing belts with help from friendly forum people/relatives with the cars I drove in my previous life). Thanks!
