1997 Lexus LS 400 - Page 8 - Answered Questions & Fixed issues

Take your battery in for a load test. Betcha a cell has dried up. Will probably survive but I would still trade it in.

If the tensioner is broken and cannot move then the only other option is to cut the belt, remove and replace the tensioner.

This usually indicates that the engine has a leaking head gasket. Do not run the engine with this problem, it will damage the cylinder head(s).

First. Storing anything that is Gasoline powered for a long time ( typically over 6 months) should have a full tank of fule with Stabil or simmilar product in the tank and fog the engine. ( inducing a engine fog according to product lable)
As for your car I show that the Lexus LS400 has no external fuel filter. ( Poor Choice by Toyota in my opinion) the only filter that AllData shows for your car is in the fuel tank. If you have not *** of yet. I would find a place that sell Castle FireBall. It is the best injector and fuel system cleaner I have found. Try that first. If no luck you may have to try a professional injection cleaning. That would be my first try, if you have ruled out vacuume leaks. Letting a car sit can also cause dry rot of vacuume lines. Look it over good. Spray carb cleaner while engine is running on vacuume lines and see if you hit a spot where engine smooths out. if so that is a sure sign of a vacuume leak in that area.

the smoke is from engine oil, it is caused by leaking valve seals , after the engine is shut down for the day oil is leaking past the valve seals and getting into the cylinders then when you start up the engine the oil is burned off, this is a common problem, and there is a couple of things you can do to help the problem with out taking the engine apart and replacing the seals, try this first at your next oil change add some Restore to the engine oil it will soften the seals and give them a little more life, if this does not cure the problem after a few 100 miles then you will need to have the seals replaced, and this is a costly repair, but you could just live with the smoke it wont hurt any thing just keep an eye on the oil.

Okay this one one of two things, first this car uses two distributors and the rpm signal which is the code 13 comes from one of the distribntors i forget which one but it could be a bad distributor but note that ive run into this and replaced with aftermarket one and the check engine light kepted coming on until i got a factory distributor for dealer, the only other reason would be the timing belt is off a tooth or two, i would make sure that timing belt is dead on. good day.

Hi, you probably have a loose linkage inside the door that connects the lock to the handle. You have to open the door panel to trace and replace the loose linkage and if you need a picture diagram for this purpose, you have to get your car repair manual from Haynes manual.....

IF THE BRAKE ROTORS ARE WARPED IT WILL CAUSE THE SHAKING. BUT YOU WILL ALSO FEEL IT IN THE BRAKE PEDAL.

Thanks for choosing FixYa and welcome to the site. A easy way to trace the filter is by going to the gas cap. Whichever side you fill gas at. Get under the vehicle and follow the gas lines that lead toward the front of the car. You will then run into the filter.

It should run ok, it might not get as good as mileage you would with premium and it might not have normal performance as with premium.

The low coolant sensor could be stuck...this is located sometimes in the bottom of the overflow tank...(a light tap can sometimes correct) or some are located on the radiator...follow the electrical lead...as long as coolant is circulating properly...this is probably the culprit...if the sensor is on the radiator...a light tap applies too...you can disconnect periodically as this sometimes can correct...Hope this helps.

If you can afford a Lexus, you can afford to call a dealer service department and have them bring you out of the dark about their coded keys.

P1600-This Relates to Powertrain Control Module Battery Backup Circuit.It will only reset if it is either an intermittent fault or has been repaired.This module and wiring will need inspecting,testing and possible replacement to enable resetting the flash code.I hope this helps,or get back with your findings based upon this info and we can move towards a positive repair solution.

Hi, normally there is always a copy of the fuse box diagram in the fuse and if you can't find it there, then you should check inside the car manual which is the next and only place you can get it.
If you don't have a copy of the car manual, you make order for car repair manual from Haynes manual, you will get it there.....

bank one is always the same side of the engine as the number one cylinder. Bank 2 is always the other side.

Is the check engine light on? If so it may be on because of a bad o2 sensor, bad o2 sensors send signals to the ecu which adjust fuel mix to the injectors. If its not a o2 sensor you may need a new computer they can malfuntion also. There's many sensors and models that control fuel delivery. The ones i've mentioned could be the likely source.
