I have owned this RX300 for a little over a year. I am the third owner. This car started out as a leased vehicle. The engine was blown while a leased vehicle and was replaced when the second owner bought it. there is 60k miles on the engine and 115k on the rest. Now to my problem.
I started my car yesterday when I put it into drive the car died. I restarted let it run for about 2 minutes then was able to drive away. When I went to lunch had the same problem waited again and worked. When I was returning to work from lunch the car wouldn't start. It would turn over want to start then die. I could get it running if I gave it gas however if I let off the gas it would die. I was able to drive with two feet to get it to my father's. (my dad is a mechanic)
We checked the fluids and everything was ok. I also had no gauge lights on while driving. When he check the codes he couldn't reset P1136. We found out it means lean fuel, however my father is not a Lexus Mechanic so all we did was check the PCV value to make sure that it worked. I cleaned it out. We are hoping someone could get us going the right direction.
I also recently had to change the Battery. That was 1 month ago.
Thanks in advance!
