My 92 ls 400 has become hard to start with the accelerator pedal having to be depressed in order to start. will not idle immediately after starting until engine is revved up in excess of 2000 rpm.
after initial start and idle problems it runs fine.
do not have lexus dealer in my town and the snap-on scanners do not pick up codes
we replaced the two front o-2 sensors on the advise of a lexus parts man who said that they never even stock the two rear sensors
replaced the tewmperature sensor also but neither appeared to help
have 136000 miles on the and have not had any problems in the past
