Personally I would try cleaning the airflow meter. Won't cost much (say £3.50 for an aerosol of carb. cleaner) and could cure the problem Be V. gentle with it though.

 

Not much else to suggest unfortunately. The N/A's are pretty bullet proof (I've just removed a turbo conversion we did from my Lexus 1997 GS300-same engine as yours).

 

Oh, and this is assuming you have no air leaks. Which are a Very Bad Thing where airflow meters are involved.

Very funny Ash:twak: :D

 

Cheers for the feedback Nathan . .very good of you. Minnd my ignorance :stupid: but which one is the airflow meter ? I clearded out the carb last year where you spray some "stuff" (excuse the technical term :D ) direct into the inlet manifold at specific revs ??

H, You can see the airflow meter just behind my inter-cooler piping, the little black box, with some wires coming out of it. If yours isnt 96> or UK then I doubt it will have one.

 

Hopes this helps.....

Remember this is an N/A and therefore the inlet layout looks a bit different. Not vastly but if you asking where the AFM is in the first place...

 

Someone on here must have a pic of the inlet/AFM on a Soop?

 

If not, I'll take a pic of my GS300 tonight....it is identical.

 

Also, look carefully for any split pipes between the AFM and the inlet manifold. Anything even looking slightly dodgy should be investigated and rectified.

 

Cheers,
