Hey TACH, thanks for the help in the past. I have a question about timing on someone else's 96 LS400. (not on my 93) It's another member but I'm not familiar with the interference motor. Before the T-belt was taken off all three timing marks were lined up. (crank and both cams) Turned it another 50* after TDC. Pulled the belt off, worked on couple other things and the L cam pulley (drivers side) accidentally got turned a little bit, maybe another 10* clockwise. The crank and R cam are still where they were before the belt came off, 50* ATDC.
Question is; should he spin the L cam counter clockwise back to where the timing mark is supposed to be? Or should it be turned clockwise to get to the timing mark? B/c it already spun 10*, if he goes clockwise it will go another 350* to make one full turn, (360*) on the L cam only. Would that cause damage? Remember, the crank is still at 50*ATDC. He doesn't want to hurt anything with it being an interference motor. Now, he tried going counter clockwise and says there is resistence, I don't know how much resistence like if it's solid or like the spring is compressing. He's getting different answers so I figured I would help him out more and ask an actual Lexus tech. I appreciate whatever answer, thanks.

When I insert the key (master key? black plastic fob with three buttons - trunk button not functioning, by the way) The security light flashes and the car won't recognize the key...for over a minute sometimes. I can turn the starter, but it won't fire up. But after a time, I hear an audible click, the check light engine comes on, the security light quits flashing, the tach needle jumps to life, and the "P" lights up. Then it starts, every time.

Also, I have a copied key, from Ace Hardware, that will open the door, and will eventually cause the security light to stop flashing, but usually doesn't start the car.

Any thoughts?

Thanks,

It'll blow cold, then all of a sudden it will blow hot. Compressor SEEMS to be cycling during both temperatures. I had it evacuated and recharged, and all of it was there.. so no leaks. I havent had gauges on it tho, since.. is the compressor common? I was hoping ambient switch? Sunload sensor? Help!

Hi I have a 1999 GS300 with just over 140,000 miles on it. I recently had the brake booster assembly replaced. Before it was replaced there would be an awful squealing noise which would end in a high pitched buzzer sounding and these four lights turning on on the dashboard: VSC, ABS, VSC OFF, and the red BRAKE light. Replacing the booster assembly did the trick. However, a few days after the replacement, the VSC, ABS, and VSC OFF lights came back on but with no noise and no red BRAKE light. Could it be something with one of the brake sensors? If so, how much do they usually cost per sensor? The second issue is a noise coming from the engine. It happens when the engine is between 1,000 and 1,100 RPM. The noise is a rattling, metallicy sound. Could it be that some piece of metal near the engine is loose and the frequency from that RPM range makes it rattle? Thanks in advance for your help!
