Maniek, how much cheaper is diesel?

Prices per liter (gallon is 4,55 liters)

PB 95 ~ 1,17USD/liter

PB 98 ~ 1,29 USD/liter

ON (diesel) ~ 1.17USD/liter (from about 4 months diesel is like PB95)

LPG ~ 0,68USD/liter

My car is converted to LPG :D and takes 20 liters/100km

.. wit the fuel prices these days... n i checked today... $2.74 or $2.77 :cries: realli hurts ur wallet.

Let's visit europe :cries: and buy one galon of gas for 4,50-4,70 USD :cries:

i have a 93 LS400 with 145000, my gas milage is 12-13 city,i had the timing belt, plugs,wires,cap,rotor,vaules adjusted,o2 sensors where change in the last 5 month. i get about 230 miles on a full tank of 93 octane.

Did you change air filter & fuel filter also ? Its are most responsible parts of fuel consumption.

Second: try to clean iniectors using special liquid.

Third: How are you driving your car - "binary" stop -> hard start -> brakes -> hard acceleration -> stop ? If yes - it is a normal that car will take a lot of gas.

Fourth: How long is usually your one trip ? (if very short - it is a normal...)

Hi,

My engine has a poor condition and I have two options: 1. do rebuild 2. buy 'new' used.

Today I found SC400 after rear accident with excellent condition of engine. And now is IMPORTANT question:

is it possible to do exchange those engines ?

As I know SC400 had more horsepowers than LS400, but I suspect if it will fit my car ? I thinking about adjust of ECU and other (which ?) thinks ?

On Monday I'll visit my mechanic and ask him, but your opinion will be valuable.

My LS is from 1992, damaged SC400 is from 1995.

Thank you

Just checked your web site. That is a sweet LS. I like your wheels, too. What brand are they? Are they 15"?

Thanks :-) Wheels are made by DEZENT (it is a German company) model T. My current rims are 16" (I bought LS on 27th Oct and sold camry 28th Oct) and wheels are from my 'old' car. They look so small, because tires are 215x55x16 nor 225x65x16. After I repair engine I'm going to buy the same model of rims, but 17" or 18".

Thank you again.

p.s. can you please send me wiring diagram of LS (directly on mail mmilobedzki(at)gazeta.pl)

Cool,

First - thanks for manuals - I'll back to you when I need something (e.g. wiring diagram)

:D :D repaired :-) ECU said true there were BROKEN circuit on the right speed sensor. Previous owner or mechanic or ... broken plastic which hold sensor cable to timing belt cover. And then cable was impend over cleat belt which regularly rubbed isolator of cable until damaged it.

Now car goes like before buy - on 7 cyls. but without Check engine light ON and without engine shake.

One thing more - when engine reach 5000RPM (after kick-down) is seams that speed goes down , AT not change gear to next one (up). After about second gear is shifted and RPM is about 4000 and accelerate to 5000 and again slowly, change gear and goes up . On a camry when I kicked down there were a power from 4000 till 6200, fast next gear (RPM back to 4000 and fast went to 6200 again on the next gear) until I reach 120MPH or more :-) Now my LS is very slow (in accelerate) comparing to camry :-( I'm unhappy on that..

Was the car performing badly before you worked on it?

When I bought LS - it not worked fine (only on the 7 cylinders :-( on the one of cylinders there is poor compression - on 90% diagnosed as crooked valve) On the idle engine working on 7 cyls but when I accelerate to ~2500 RPM or higher is better.

You said "after a few days, when it was raining" you noticed the problem. Are you saying everything worked fine immediately after the work you did, then later the trouble started?

Yes I replaced those parts at 28th of Dec, and noticed problem yesterday :cries:

When you say "after 2-3 minutes" everything is fine", are you saying when the engine kicks down to idle speed (~600 RPM)?

No, I saw no rule when Check engine goes off (sometimes during normal drive or on the idle.

E.G. few minutes ago I ride very fast - and for 3-4km check engine and TRC were ON I stopped a car for 2 minutes and go back home and during 5km there was no Check Engine ! Now I coming to garage with multimeter and will spy were is a problem..

You might have a short in the throttle position sensor, or it may be stuck open. Are you asking for the location of this sensor?

I checked that code 1-3 is responsible to SPEED SENSOR, but I'll check TPSes also (I have two - is it true that one is for TRC ?)

Do you have the manual for the 1992?

Unfortunately not :cries: I'll be very appreciate if you can share it to me

Thank you

I'll update thread tonight when I back

LS 400 1992 EU

"WMLY 666"

Hi,

I'm still new in LS. Last week I changed (all parts from dealer):

- spark plugs,

- wires

- distributor cap

- distributor 'finger'

Also cleaned throttle body (according to http://www.lexls.com/tutorials/EFI/throttlebody.html)

After few days (when start raining) I saw Check engine light on + TCS off started blinking and sometimes went off. Engine has no power and I feel that is not working on all cylinders :cries: But after e.g. 2-3 minutes check engine light goes off and engine is working fine.

I read engine trouble codes (TE1 + E1 connectors) and got: 1-3, 3-1, 4-1.

Can you tell me (best show on the engine photo or schema) where speed sensor is located ? If you know where are wires under the hood will be great.

Thanks a lot

I noticed the same on my LS :( From start to 60mph my car need about 12 seconds :-( I just replaced spark plugs and wiring (both bought at dealer shop).

My engine is also loudly when cold - something is knocking. Can be required adjust of valves ? Is it possible to lose power through improper valve clearance ?

My three previous cars were camry s 3.0 with 1<Z-FE engine and they much better accelerated that my LS :-( I am unhappy on this fact.

Can someone give any advice where can be a problem ?

My car is LS 400 EU 1992 with 110k miles.

Thank you
