i have a 92 sc300 5spd, and i love my car to death but i think i'm at the end of my rope.
see when i bought my car it had 55000 miles on it, really low for the year but i got it from a dealer.
it ran really good, and the first week i did regular maintaince, oil,tranny fluid, diff fluid, coolant and everything was fine, the next couple months the car felt slugish and sputtered a little, this is when i signed on to clublexus and the first day i found out what to do in detail and i was very thankfull, i changed the cap and rotor, plugs and wires, and changed the ignition coil, and everything was fine.
It is now about eight months later and just like that out of the blue i started getting a strong fuel smell and non stop white smoke from the tail pipe, and the gas just vanishes from half tank to almost empty in only a couple of miles and it feels like i'm running on 4 cilinders, it's been happening for a while so i took it to my machanic he was stomped, so i took it back and it stoped on it's own, and i drove it for a week with no problems, then today it started again.
i'm on the verge of taking it to lexus, better get my greese out huh
this is just my last cry for help, but before i sign my *** over to the shlong dealers i think i'll try a couple different things to see if it helps, but anyone who had this problem or can help me out please do i am really stressed out.

thanks in advance
oh yeah i now have 80000 miles.

What did you search for?

Search for 'smoke' and you'll find the writeup I found on smoke (including white smoke) on a recent post.

thanks alot i'll look now

 

hey i looked and i found some stuff but not exactly like my problem, thanks for helping thou, but i got frustrated and took it to lexus and to my surprise they did'nt charge me a dime, they said that i have too many aftermarket stuff on the car, ie( intake, msd coil, electric fans, exaust, and a air fuel meter) woohoo for all my aftermarket stuff, but believe it or not i feel worse than i did before i took the car to lexus.
but something interesting hapend today, it started acting up again so i cheaked the oil and there was smoke comming from the dip stick tube, please tell me this is'nt too bad

 

sounds like theres a whole lot of pressure where theres not supposed to be. Look into anything that can be causing it, mainly a clogged pcv valve. I doubt it should be so much to make it spit out of the dip stick tube, but it may help.

 

i'll cheak the pcv valve, but how long should a pcv valve last any way, i changed it a couple months ago

Sounds like you got too many problems in too many different places. Sounds like crappy installation job.
Along the lines, someone, somehow, tap the wrong wires for all your stuff.

I would put everything back to stock. Accept the exhaust. Then see what it does from there.

 

PCV valve lasts like 90k miles or something, dont worry about that if it was recently changed. The smoke coming out the dipstick tube...I dont think thats a problem, it happened on my old car all the time.

i dont know what to say man, sorry

 

thanks, but i don't think its crappy wiring cause i was an instaler for two yrs, and i did double cheaked everything, so i think the wiring is fine, the car drove for about 10,000 miles after i put all the stuff on, so i'm like 10% on bad wiring, but i'll cheak it again.
someone told me to get a leak down test, what exactly does a leak down test cheak for?????????
