I end up change the electronic unit (MAF, AFM) only and it's all good now....

I bought two MAF..... just in case...

Now I need to sell one....

I pay $100 + for it and now selling for $90 shipped

PM me if anyone is interesting on it

CRC for the MAF is fine. I was happen you did not say seafoam here.

Is the engine cold or hot?

Should I try seafoam?

Engine is cold.......it die too fast.....

no help when add gas.....

did you just spray the aerosols into the intake, or did you disassemble anything?

I clean it like this

sounds to me like a vacuum leak

How do you check it?

How to fix it?

when I removed the parts I see the silver stuff between it, is that something to prevent air leak?

why it is fine for the first 30 sec? :(

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?
