Thanks for the advice guys, I already read the procedure and i'm having a buddy of mine that is very good w/ cars help me out w/ it. Lets hope this fix's the problem =)

I had a complete flush 2 days after I bought the car (2 weeks ago) , didn't have thermo replaced so i'll be doing that this weekend, hopefully replaceing the thermo will fix the isssue. Thank you guys

Picked a fuel filter up last night and was going to install after work today. A buddy of mine recommended. I don't know when the fuel filter was last changed. I just bought the car 2 weeks ago. Thanks!

Well then the problem might be bigger than a thermo. b/c i've done what you just stated. ;)

Thank you, i'm going to replace the thermo. and see if that changes anything. Thanks again!

Well now a new issue has arised. I noticed this when I was coming to work this morning. I was on the highway and at around 75 / 80 mph the car started to buck, no knocking noise or any noise at all but just like lose of power then it was fine after 85, and be4 75.... any ideas?

It is not on auto, i've tried all the setting, like i said be4 its fine for the first hour or 2 then it just starts to kick back and forth from hot and cold. If i shut the car off and back on it doesnt fix it. I let the car sit for 2 hours and its back to normal. Its only on long distance trips that this happens. Starting the car in the morning it heats right up w/ no problem. Im clueless...

Hey guys, I just purchased an 93 LS400 and noticed that when driving for an extended period of time after about and hour or 2 the heat will start to blow cold and hot. What could be causing this? Its 20 degrees Fer. and it can be a major annoyance. Plese help!
