Hey all, I'm hailing from south of Denver with an '01 LX470. It has been the subject of a few threads on here I believe, from the previous owner a few years ago. I have been an occasional wall fly for the vast knowledge here over the years, for my '93 LC and now this beast. But figured I'd join in the fun instead'a just listening from the stands.
The LX470 has been having issues, random total power loss with rapid acceleration, randomly losing acceleration capabilities at all with the sputter-putt affect, randomly occasionally dying, and finally last night died and would not start again. All issues I have found on here. All very fun issues on the highway...or in intersections...or in parking lots on 10 degree nights... finally had to have it towed back to the house. Being my wife's daily driver, it's time to address the issue.
That lead me to some testing, and so far the APPS tests good, haven't gotten to the TPS yet. The garage is like 40F and still wet with (barely) melted snow puddles....I don't wanna! hehe.
As I was going about this, the second time I turned the key to on position and moved to the front I heard a really ugly high pitch buzz/whine coming from the throttle body. It got louder as I tugged on the throttle cable. The Throttle plate was engaging, but it didn't appear to like it very much. Then the noise stopped and TP stopped responding to the cable.
A few minutes later, I tried key-on position again and got the buzz, but it never stopped. Just kept on hating being a Throttle Body and screaming about it. Again, throttle plate responded to cable, but it screamed progressively louder with more pull.
I think it seems to be coming from the Motor assembly side of the TB . With the help of a listening stick, it seemed louder on that side. I have seen a couple write ups on different TB's that mention the gear/clutch causing issues that sound like this. Has anyone here seen (heard!) this problem on the 100 series?
I am highly considering just replacing the whole TB but feel like if I can just do the motor confidently that I might rather do that. It sure is a little less, but is it a sure thing?
Any info or experience would be great. Thanks for all your wisdom mudh8ers!!
