Do you have a chk engine indicator lit??? Check for cracks/leaks on your air inlet hoses that connect to the air flow meter to the throttle body (intake). Timing or faulty ignition system could cause this, but is very rare on these 1UZ V8s.

If you have not changed your air and/or fuel filter recently, that is a good place to start. Also check your spark plugs and make sure they are gapped properly (.044"). you might also have a vaccum leak somewhere.

Car wont start due to ignition Coils wont give spark (sometimes)


Okay, I am not convinced it is the spark. But there is a chance. The fact that torching the plugs allowed it to start tells me you engine is flooding. Do you smell gas? If you open the throttle body with the air cleaner off, does vapor come out when the engine had recently cranked? If it is electrical, then power to both ignition modules is failing, which means A. the ECM is not providing power to the modules, or B. The engine crank sensor has failed. The Cause could be a bad connection to the ECM.
A scope will indicate whether or not the proper pulses are being input and output from the ECM to the modules. Of course it will need to be tested when it is not working compared to when it is. When cranking, the tach should move indicating rotation of the crank, if not, there is a good chance the crank sensor is no good.

How to remove headrest of a 1990 lexus LS400 power seats, can you help please!!!


On both sides of the headrest spokes are little adjuster rings. Adjust the headrest up to the highest position. Push down on both of the adjuster rings. While doing that, pull up on the headrest and it will pop right up.
