My experience with the SC400 last year is complicated by the technology, and terminoloy, i.e., the following recommendations:
The problems were not completely diagnosed since the scan tool wasn't communicating with the ECM; the EGR system was not operating and was completely replaced; the motor mounts were also collapsed.
I haven't replaced the ECM or the motor mounts yet; the ECM was quoted between $1,500-$3,000, so the motor mounts may be the next project for 2013.
Thanks for all the information in 2012; the results of the next maintenance year, 2013, will be reported to the Club Lexus Forum. Hope that helps.
Check all of these....
Check then recheck..
MAF
IACV
TPS
all four 02 sensors
plugs
wires
caps
rotors
coils
then check the timing
bad ecu
the first thing I would do is the fuel ecu mod, its cheap, fast, and could immediately fix your issues....
