start up until it sets for 5 to 10 minutes.?
What part causes this car to run about 30 to 40 minutes then shut off and not on 1994 Lexus ES300
your car just got the same problems my car,i did troubleshoot,it is ceu/cem problem and shift solenoid E electrical problem too. you need to change a new CEU/CEM MEAN Control electrical unit/ control electrical motherboard specailly it call computer box.and shift solenoid E electrical code P0773.it is transmission problem.don`t buy CEM at dealership it is too expensive it cose about $320,but if you order online it about $199 or less.at junkyard about $75 but it hard to find it because alot of people took it all.
i would start with a fuel pressure check.
