Integrating the simple elegance of the new Lexus design initiative with racing–inspired style, sculpted curves and fluid lines make a dynamic statement.

      Oh no, not another alternator ...

      By threepwood · Posted

      92 LS400.  ~180k on it, but can't say for sure as Odometer quit at 157k (ah, just another known issue, eh?).  Have replaced alternator 2 times before, both due to power steering leaks, but the failures were different than this time.  Previously, they just quit and all idiot lights on dash came on.  This time idiot lights come only below 1000 rpm.  volt meter on battery shows it is not charging below 1000 rpm.  There isn't any belt noise,  but I have.....Changed belt out belt with spare I took off just because of old age at the 100k service,, removed. cleaned and replace both battery terminals, Applied belt dressing, applied tremendous pressure with engine running on tensioning pulley (quite a dangerous trick I don't suggest if you don't know what you are doing).  Although I have never seen an alternator fail in this manner, My conclusion is bad alternator again, this time NOT associated with leaking power steering.  Any other thoughts before I pull it ?

      92 LS400 Coincidence? I don't think so but maybe

      By threepwood · Posted

      Sorry this is a late reply but for some reason this post is not sending me email messages that a reply has been posted.  Moet_lowlyfe.  I had similar problems and I got a second ecu off ebay and it did the same thing so I thought it was not the ECU.  Then, one of the staff members here convinced me that the ebay ecu was probably also bad !!!   And sure enough, I bought a capacitor kit off ebay, replaced all the capacitors on the ebay one and put it back in m car and all driving issues are gone.!!!! So I bought a second kit and did my ECU.  Sure enough, I now have 2 good ECU's and the car runs fine with either one and this #1 cam issue happens with either one.  Before anyone asks, no, I'm not looking to sell my second working ecu, it's now part of my spare parts. 🐵  My suggestion, get a kit (only around $15 on ebay) and replace those capacitors !!!!

      have a 98 ls400 with a 1uzfe and just last year i encountered this same problem. On a cold start it ran well until the motor was at operating temperature then would drive like s#*t as if it was mifiring. A few times the vsc light would come on check engine light stayed on. So i took it to my local shop found an air leak on the intake box, changed plugs, did a compression test all cylinders passed. Put it all back together and still did the same thing. I took it to another one of my mechanics who had a better diagnostic computer codes came back and said faulty vvts (variable valve timing solenoid) replaced those as well as removed the valve cover and cleaned the screens. I must say for 400xxx miles there was not any serious sludge. Put it all back together and still same problem. Later i changed timming belt ,tensioner, idler, guides even put new vvt cams in. Problem still continued, my buddy had a ecu that we tested and problem continued to occur. So as of rii now car has been sitting for more than a year
