Probably your alternator is gone due to PS leaking pump. Check that out too.

I had a similar problem. It was the left coil (driver's side) wire. Open the hood when engine is running in a dark environment and check for any fire works. Good luck

Did you change the tran mount? Any pics?

Well I got up with a game plan today to go deep into this problem and hopefully fix it. I changed the MAF Sensor, (again) TPS, COIL, IACV, ECM, fuel pressure regulator, secondary TPS, hoses, wirings, etc, etc, etc. I did all the possible fault isolation I could think of and nothing did the trick. After tricking the fuel system I changed the fuel pump and the car is back in business. So now the car is working fine again but I have all these LS400 parts in my garage, all of which works fine but none of which can be returned. I may open a used parts store until I can get rid of them. Thanks for the assistance all, CuriousB you devotion to helping others here is note worthy and I appreciate you time. I have plenty of troubleshooting steps and maintenance for the 91 LS400 in pdf file format if anyone need some information. I am glad you finally found the problem. Why not attach the PDF in your next posting?

Pay a visit: http://www.lexls.com/tutorials/EFI/throttlebody.html http://www.lextreme.com/tb.htm Thanks for the links. Good write-ups. Looks like a fun job. Looks more involved than I thought, but this is coming from someone thats not a DIYER. <_< I will give it a whirl though.... whats the worst that can happen.... I break a $500 part? I have done it myself. I am not mechanically inclined and I had put the screws in distinct places to remember the way going back. Up until I joined the forum very recently the dealer was always getting my repairs/maintenance money. I do though have another two cars, IS250 AWD and GS350 AWD. Eventually, I can not beat the system but as far as the old lady she will get my love and tender as far as I can in my garage. Good luck.

Thank you, now I got a project. Best Chris

Then what? What's next? I do not have any brake problems so far but I noticed one day after a short trip when I cleaned the wheels the left front was really hot but not the right.

I had very rough idle at traffic lights and stop signs, hesitation, pushing the gas pedal and engine was dying. The problem was a short on the driver's side coil wire. Black electrician tape eliminated the problem. If the car is in the carage open the hood and see for any fireworks in the engine. Just my two cents. Good luck

That's really a good one :D :D :D :D Regards from Darien

The ring/band is there, it is not the photo, that's why I posted the pictures. What is approximately the minimum pad thikness? Thanks,

My last complete brake job (four wheel pads, silencers and rotors resurface) was done by the dealer for $657.28 in 4/24/01-100,872 miles. During one of the routine oil changes in 04/03/04-116,228 miles I asked the dealer to check the brakes too. He said the pads had still another 75% life. Now at 130,000 I do not have any brake problems yet but I try to be pro-active. Do you see any signs for any repairs? Left Front Right Front
