  1. Hey guys friend of mine is working on my LS400, I have really rough idle which seems to be a common issue here and stalling while driving has happened twice, no acceleration at idle, and problems are getting worse over time. However with the fuel pump relay at 12V things are working fine, changed the fuel pump relay resistor based on another tip here of someone with the same issues, that didn't solve the problem. Any other ideas? Don't want to do the fix and replace, could it still be the fuel pump even though it works at 12V?
  2. I have the same problem, 92 LS400 idles rough, it died while actually driving once, found out it's the fuel pump relay resistor. Works fine maxed out but can't find the resistor to replace it. http://www.clublexus.com/forums/maintenance/229393-ls-400-stalling-problem-solved.html
  3. A friend of mine is working on my LS400, the car was stalling while idle and also completely died while driving, he set the fuel pump relay to run at it's highest and the car is smooth now, he found the fuel pump relay fine but he can't fine the fuel pump resistor that controls the pressure. I've googled all over, nothing, I also don't see a Haynes or Chilton manual for this car, do they not exist?
  4. Clean up the battery connectors with a wire brush and be sure bolt torqued down well. Replace rusty bolts with new. Loose connections won't allow the 200-300 AMPs a starter motor will draw. Other things working but they are a very light draw on battery compared to starter motor. Yeah, the positive female terminal is completely corroded on the battery. Might have to be replaced but that's a hell of a lot better than the starter if it is it! Thanks man for the tips will get some new bolts too.
  5. I'm guessing very likely I activated the anti-theft. At least I hope that's just that. Any thoughts on how to disable?
  6. Update: Disregard title, it will click. My female positive terminal is completely corroded on a 1992 LS400 so much so that also me being new to working on my car grinded into the positive pole of my male battery. Also if it's not in the right position it won't turn on or get power. Right now though I can turn on my brights, radio, and A/C and still just get one click.
  7. Replace the hose...it runs at a super high pressure. That is my 2 cents. Thanks for the advice. Yeah looks like it's $150 around TX unfortunately, the tech said that as well but just checking.
  8. Hey guys I need some advice. I had my LS400 1992 worked on for the A/C in another town and the guy said there's a leak in the hose, specifically the high side hose from compressor to condensor that was leaking freon, does anyone know if this is patchable, how much this should cost to fix or if this sounds legit? Thanks.
  9. So I've gone through a few speaker sets mistakenly that aren't quite up to par with my previous speakers. I changed out my receiver and can't get my sub working so I'm in need of bass. I loved the old ones but one of them was distorted and broken. Is there anything comparable on the market? They're dual cone right? Anything that matches them in range or any official specs on them? Would love it, thanks man!
  10. Or to add to this, which wire on the original car stereo wiring is the ground wire for the amplifier for the subwoofer?
  11. Hi thanks man for your instructions. I'm also trying to do this on my LS 400 1992. I'm trying to figure out though which wires from the original car stereo relate directly to subwoofer? I had one one of the pink and blue wires on there and the sub worked for a few seconds but then switched off. Came on and then turned off. Does something else need to be grounded.
  12. Hey guys, After reading the forum searching for answers it looks like the Michelin MXV4 are the tire to get for this but I was looking at some other options. I had Michelin's on my last car, a Camry XLE and I replaced them with Goodyear Tripletreds and overall liked the ride more and felt they had better wet traction. I'm trying to figure out the requirements for the 92 LS400, looks like I can't go with Tripletreds again because the rating might not be enough but the only thing I'm seeing as rated lower is the load rating and 99% of the time I'm driving alone. The Primacy is load rated at 94 and the TripleTred at 92. Would this be a problem? I've also looked at the BFGGoodRich, do I need the higher "V" speed rating? Again 75MPH is my normal speed on the highway and I almost never go above it, 80 tops. Any input would be appreciated, thanks!
  13. Never mind. Somehow I posted in the wrong forum. Please delete post.
  14. Thanks man! I dug my Camry as well, about to hit 191K miles and I'm sure it would have gone another 60K but wanted a change of pace. I think I will go premium or midrange since it isn't a huge difference.
  15. the flames he's referring to are a term we use for people who bash others needlessly. regardless, I'd bet money that the '92 you're looking at still has the OEM plugs and wires, probably timing belt and water pump too. Don't pay a penny over $4k for that car unless you're absolutely sure everything down to the water pump has been replaced, with dealer records. Also, there were significant changes made in '93, most notably bigger tires and brakes. That's the oldest you'll want to buy a used LS400 unless it's a super good deal (what you're looking at isn't). Thanks again for the pricing tip, it is in an amazing condition which is why I'm interested but I'll try and make them come down. Just some elderly person who lived literally blocks away from the dealership drove it and it's so pristine, I'm excited! :P I've been looking for a 93-94 as I read that model is definitely better but I can't find anything either A) with lower mileage under say 140K or B) under $8,500. Maybe they're more expensive around Austin? But I'm gonna try and have them knock the price down even further, thanks! If I do get I'll report back with pics, already loving all the extra detail all over this forum!
  16. Wow, I felt reassured until that last sentence :P Sort of cryptic. Yeah I just drive to work, fairly steady...However uh, unsure if you were being sarcastic :) It's not much more I guess but if I don't need it, since I rarely go above 75 then I wouldn't. I like that the power is there if I need it but I'm getting the car for a smooth ride, reliability, safety, interior, and resale value.
  17. Yeah that's true. And I just found out that USAA, at least from the quote from their website, drops my monthly insurance by like $60 a month. Have to see if I actually get it then but that should more than cover the price difference in premium gas and maybe even MPG between the Camry XLE 1997 V6. I dig the Camry but never liked the color (gold, the lexus is a nice dark green) and it has amazingly 70K more miles than the 120K miles on the 1992 Lexus ES400 I found. So it's probably worth it, hopefully I'll be joining the club soon. :)
  18. Damn that is too bad. With the price of gas these days I don't think I can afford that. Other people have the same thing happened using 87 octane regular gas?
  19. I'm looking very closely at buying a "parked in garage" in excellent condition LS400 1992 with 123,000 miles for about $6,500. One question though, I know it gets worse gas mileage but I'm going from a V6 Camry XLE that already only got 20-22, but do I have to have premium? No need for whatever power boost the higher octane gets, just don't want to damage my engine. Going to buy tomorrow morning or it might be gone so would love replies and thoughts soon if you got them! Thanks :)
