I have 1993 LS400 with 150K miles. When I take the leg off of the gas pedal coming to a stop it dies once in a while. Takes about 3-5 minutes to start and runs well after that. It only happens once a month or so but it is dangerous due to loss of steering and brake. Sometimes it also does not start in the morning. After waiting for 3 minutes or so it starts. It cranks but sounds like there is no fuel. Use of air conditioner seems to cause it but not always. Changed fuel filter and air filter, cleaned fuel injection. Mechanics don't know how to fix it because the check engine light does not come on and there is no code. Any ideas on how to fix it? Is it the defective temperature sensor. Thank you in advance.

 

Hi blklexus

Maybe we have the same problem?
