car steady at 757 though
whats the problem?

But my rpm meter have 950 rpm

I think you may have a small vacuum side air leak. That is, somewhere after the throttle body but before the inlet valves air is being sucked in.

Hence lean condition and faster idle.

Here is my engine picture, can you please label me with red arrov where do I look for vacum leak

Per piacere.

La tua foto è assolutamente inutile per questo.

Sai cos'è una farfalla corpo farfallato?

Sai cos'è una valvola di aspirazione?

OK, quindi la perdita di vuoto può essere ovunque tra i due: una guarnizione, un tubo, ecc.


Your photo is absolutely useless for this.

You know what a throttle body butterfly is?

You know what an inlet valve is?

OK, then the vacuum leak can be anywhere between the two: a gasket, a pipe, etc.

Yes its strange, tester say 750 rpm the car rpm meter is 950rp, they must show the same number

No. The software says what the requested idle speed is, the guage what the actual rpm is.

How do you account for the difference? Well, lambda 1 indicates a lean condition, which suggests excess air.
