Hey didnt want to start a new thread for this Q so hope no one minds if i hijack this one. The tach needle illumination is not working on my 93 ls (the needle still reads rpm i just cant see it), everything else on the dash works. Please dont tell me it means taking apart the dash to get it back :cries: ty david

trannys back together cannister is in, trac light is gone but i still have the jerky feel on take off, it revs then launches. im thinking the o/d light is a resault of a bad cat, they smell way to hot and could be causing a o2 sensor to trip. the o/d light comes in 2.5 second intervols.

actually scott your probably right i flipped through my bills and it was july 10 i had it in at the dealer, maybe its time to take it back in again. i still havent tried what shelly said with the brake fluid i have taken appart my tranny and finnished installing the charcoal cannister.

I had a diagnostic a while ago at dealership nothing was wrong so its obviously a mechanical issue

thanks shelly ill try that! the problem with my throttle is its very unconsistant, if i step on it all the power is there one time then the next its totally different. it seems like it just lugs allong allot i feel i could get out and run faster i think a V8 should have a lil more power than that. i also noticed it takes a long time to get moving and when it finally does i feel a jerk maybe i should check ATF? my O/D comes on after i drive a while and it keeps blinking its very annoying i have replaced my fuel tank cap and soon my charcoal cannister in an attempt to stop this problem, what next oxygen sensors?

today i replaced my tps with the hope of getting rid of the my unconsistent throttle response, O/D light coming on and stupid TRAC light staying on after a while of driving. I think it has cured the TRAC problem but O/D still comes on and i still have unconsistent throttle response. Im going to be replacing the charcoal cannister i hope that will get rid of O/D light but does anyone know if all ls400s have this crappy throttle control problem and if not how do you fix it?

oh thanks ive never heard of tirerack before, good site though lots of tire choises for the ls400

I am thinking of getting some wald rims in the summer so i was shopping around for some low profile tires to with them. I was told by a guy from kal-tire that yokohama avs es100's have very little road noise and are really grippy but ive never heard of anyone putting these on an ls400 any thoughts?

my rear doors dont open all the time from the inside of the car maybe like 1 in 10 times it catches and opens. Also i changed all my lights to a led blue and some times they come on some times they dont, the switch seems fine it opperates smoothly . Does anyone know whats wrong?

do you know where else you can get wires cause i was looking at some nology hot wires but they are kinda expencive like 350.00 and seem like they would be for serious preformance

I dont know how many other people have ordered spark plug wires from vitek preformance but im having a world of trouble getting my wires from them and its already been charged to the credit card. I ordered my wires back in october its now going on to january and if you try and contact them they alwasy give you the same bull*BLEEP* reply that is they moved their company and dont know where any thing is WTF!!! What kind of crap is this. Has anyone else had these problems?

Does any one know of a way to convert your stock cd changer wiring harness so it will work with an aftermarket cd player that has auxillery input in the RCA phono plug format because as usual you loose your sub by installing a new cd player but i dont want to loose my cd changer as well.

thanks for your replies i did change my airfilter when i did the tune up i dont think my problem lies with my tps or stop screw any more but i never checked my maf i think ill do that tomorrow

i know you can get toyota supra 4 pistion calipers and slotted rotors and those fit on ls400s i was looking into that for my celsior (ls400) and if you were to get ss brake lines as well it would be a reasonable upgrade from the stock ls400 brakes. not sure if that answers your question though.

what is the lowest possible safe idle speed for ls400/celsiors i know it should be about 650 but i recently changed my spark plugs / wires and while i had the throttle body off i though id clean it. now it runs at about 400 rpm it feels like i have an engine from a 69 camaro, though it doesnt seem to have trouble running at such a low rpm in canada winter can be bad for cars with low idle and i just dont want it to stall. tomorrow i was thinking of checking my throttle stop screw to see if it was accidentaly loosened and also my throttle position sensor but is there any thing else i should look for? any help appriciated thanks.
