I’m not sure if the pin plug connectors  are the same Steve cheers . 

Does anybody know if the pencil type coil packs as used on the ls400 mk4   Vvti  are the same as the  the ls 430  I’ve been looking for a full set on eBay and only seem to list LS430 ones which to seem to fit various other models but no mention of LS400

No the lambda sensors where un screwed, there is enough length on the wires to avoid disconnection as the join is under the carpets . New lambda sensor mounts  are fitted .he said he had all the tools taps , thread cutters etc if there was any problems with the lambda sensors . My Lexus is now silent .

Some more pics for you .

Welding was all carried out without removing cats , which is another bonus studs can snap and cause problems 

They also come under powerflow exhausts morecambe on Google .

Popped into to see him this morning and he will be happy to do them for £200 for everyone else . Took him about 3 hours he said but I would allow 5 to be safe .

It's a cheap fix if you have rotted out cat flanges and I know with being in the motor trade that you can only buy that exhaust y piece from Lexus £££s .

Also nice that it is now in stainless like the rest of the system .

Of course I was not sure if I could .

westgate tyres ,  Morecambe , you can google them , they have a website . 

It was done in Morecambe, Lancashire . 

Had this done today to get rid of my exhaust blowing where the cats join the y piece of the exhaust , both where rotted to nothing .flanges where cut off and stainless pipes welded to cats , then a new y piece made in stainless and slides over the two pipes from cat . Excellent job cost me £200.

Bought my ls400 mk4 lpg last June , thought I would find something that wouldn't work on it with all its electrical gizmos and I was right .

The electric arial had stopped working which I fixed with a new insert of eBay 20 quid .everything else worked and I went right through it.

I'm an x mechanic and it is without doubt the smoothest car I've been in , quick when it has to be .

Lpg means it's cheap to run as well .

It's not the type of car I normally go for as my previous was an Alfa gtv v6 , and I own a mk1 and mk2 escort , so for somebody with my tastes shows how versatile the cars are , also my missus loves it from my usual noisy bone shakers , and she gets to spend more time with me now that I'm not under the bonnet of the Alfa all the time . The common bonnet gas struts becoming weak can only be through lack of use .

Get one you will enjoy it .

Have a read of the above link , I'm not saying that's a fix but look at the symptons

I have a 98 mk4 and have tried to cure the low idle , cleaning throttle body ect and after much reading also came to the conclusion that the capacitors needed doing in the ecu , my car also won't connect to OBD reader tried two , and I get traction control lamp warning occasionaly which resets every time ignition is switched off. These faults are all listed as ecu capacitor symptoms . There was a chap on here doing kits who I contacted and was getting some more and was going to contact me , but I never heard anything .

I think if you get the ecu out and obtain the capacitors it could be easy job for a tv repairman ect someone with good soldering skills and knowledge of circuit boards .

I've just looked up my old thread on here and it's actualy Steve 2006 who was doing the kits , a moderator who has just posted above me , I've messaged him about the kits and he will probably reply to us on here now . I've lived with the problems but it would be nice to fit the capacitors and see if any of the problems are fixed and report back on here .

After reading on here for a few months finally took the plunge and bought a lexus ls 400 mk4 in black with lpg .

Have few issues with low idle and slightly lumpy , cleaned out the throttle body . Engine management light comes on followed closely by esc light warning , and I can't connect to the ecu using two different scanners , one costing thousands .

So I think a good place to start could be the ecu capacitors , have you got any left Steve and if so how do I pay you cheers Darren .

Drove the car 160 mile home, first time I've ever been up close to one never mind drive ,all I can say is wow .

I was a mechanic for twenty years and drove many cars at various dealerships but none come close

Just wondered if anybody on lpg with the tank in the spare wheel well , had found a space saver off another vehicle , toyota ect that would fit a ls400 stud pattern instead of carrying a full size wheel round .
