After I clean the throttle body and MAF on my 92 LS400, the RPM start a little higher then 1000 and idle roughly. After 30 second, RPM start decrease (I can feel the car is shaking) then engine die. start it again and it die within 10 secounds. I wait for two hours and try again same thing happen (RPM start a little higher then 1000 and idle roughly. After 30 second, RPM start decrease then engine die.)
I unplug the MAF sensor nothing change.
I use CRC mass air flow sensor cleaner and CRC Throttle body & air-intake cleaner
Any one know why?
