This might help someone. the immobilizer for the 99 lexus ls400 was behind and to the left of the stereo. then tested wire with multi-meter in the kick panel and door. the color code for the immobilizer I found on the wiring diagram. For me to with my old aching shoulders. Final done

I have gone to Alldata diy and found the color codes to connect the by-pass module to complete the remote start installion. with that said I will try to get it completed this weekend. I will follow up after completetion. alldata has electrical diagrams in color for your year model.

Thanks for your input. I haven't made a decision yet. Thrush mufflers on their sound pages with headphones might be what I am looking for. I don't want to spend the money and regret it.

I'm trying to install a remote start on my 99 LS400. I need help to determine what color the data wires are, and which wires they are. If anyone can help I would certainly be grateful. I am trying to install a remote start on my 99 LS 400. the color code for the 99 is or must be different from the 98. The color chart that came with kit is incorrect for the year. I believe I have the right ones but, the color don't jive.

Thanks; I appreciate the information. Using headphones, I have compared the sound bites of Magnaflow, Flowmaster, and Thrush mufflers. I have all but ruled out Flowmaster.

I am an older guy who has stock mufflers on every vehicle but one, a 1968 Pontiac Catalina convertible. I was thinking about a mellow-sounding exhaust—nothing loud. I was in Myrtle Beach, and an LS 400 pulled alongside at a light. It had a mellow sound that I would like to have. Any Idea for muffler replacement would be appreciated.

I was looking back at this post, and the cam end cap was removed to replace the VVTI filter on the driver's side of the engine. It was not difficult to do. The first step is to tear the front of the engine as if you were going to replace the timing belt or water pump. You will find that you will only need to tear it down to the point where the tensioner can be removed. Slip the timing belt off the cam. Mark the location. Remove the valve cover and the cam end cap. I forgot I did use a cam lock bolt to keep the cams from moving. Once you have removed the cam end cap, the VVTI filter will be exposed. Replace the filter and reassemble it in reverse, being careful to make sure the timing is correct.

I know the descriptions are terrible. The lower shaft is called the intermediate shaft #2. It goes through the firewall and connects to the coupler, which connects to the rack and pinion. I haven't got it installed because there is not enough space. Under the dash, I can not push the far enough through the firewall to get the coupler on intermedate shaft #1. sorry for the confusion I hope this clearer

I am having trouble getting the lower steering shaft replaced. After replacing the rack, the lower shaft would come back down to be installed. I replaced it with a non-tilt shaft. I now have the tilt shaft, but I can't get it to install on the steering column. I don't think I would need to remove the entire thing to replace the correct lower shaft. I can't get it to go far enough through the firewall to install on the upper shaft.

No apologies are necessary; your intention was great. That's what this forum is about: owners helping owners. Thank you for the great help always.

Yes, after removing the timing belt and the cam gear. Thank you very much!

Thanks for your input. I had no idea that there was a VVT position sensor. I found it in an exploded view while searching for something else.

I have seen tutorials for changing the VVT solenoid, but no one has ever mentioned the VVT position sensor. Does it ever go bad? If so, how difficult is it to replace?

Let's put this puppy to bed. I found a YouTube video with the cam seal being replaced. The timing belt had to be removed to remove the cam end cap. Thanks for your help and support.

Thanks once again. Paulo57509, you are a wealth of information. I was able to remove the plug from the end cap, yet the end cap did not come off. I will keep trying things until It comes out or I get weary and stop.

I checked, and the plug is in the cam end cap, not in the head. It is more than likely keeping the end cap from being removed. At this point, I must figure out how to remove the plug without causing damage.

It could be possible that the plug is causing the cam cap not to release. I tried to free the cap again. I looked at many past post and most replies came from you Paulo57509 with great information thanks you very much.

I like the way you give information. It's simple without a condescending tone.

Thank you for your assistance. I appreciate your help. If I understand correctly, I do have to remove the timing belt from the cam gear. Also, remove the cam gear to remove the end cap. So, I am retired and tired. I will take my time and do it all over again. I was hoping I would not have to do that. I was able to break the sealant, but I still can't get the cam end cap off.

I need to replace the vvt filter which is in the head under the front cam end cap. I have taken the valve cover off and removed the bolts holding the cap. tapped it to get it loose. so there I am. any help would appreciated.

I got a kit without a tensioner. The water pump is new. Everything is new, but not the tensioner . thank you

I have installed a new timing belt on my Lexus LS 400. installed the tensioner and removed the pin. Now, it appears that I have slack in the timing belt. From the crank to the left camshaft was tite, and from the left camshaft to the right camshaft was tite. From the rt. camshaft to the crank was a little slack. and I pulled the pin from the tensioner. Now, I think that reusing the tensioner was not the right thing to do. Thoughts, please

Thank you! I hope to tackle it tomorrow. The code I think was or is P1349 for Bank 1.
