rough idle, running rich

That’s what written on it

That is a glanza sensor, so should be fine.

 

[rid1ridz14]

i will have to get it check by someone if it’s really the valves

but what does the VSV do?

 

[rid1ridz14]

Will a different map sensor work? For example 3sgte 2 bar one? With part number 89420-17030. Can someone confirm for sure. Because I can’t find any 4efte one

 

[rid1ridz14]

Hello guys here I am again..
I’ve been looking around and some says waxstat
How to I go from there? Can it be cleaned?

 

[rid1ridz14]

Car has jumpy rpm on idle
And burning petrol like crazy

 

[rid1ridz14]

Any help on how to diagnose that

 

[Jay]

If you suspect the waxstat pop the intercooler pipe off the throttle body and you should see the vacuum port in the housing. The waxstat controls how much air gets into the system through this.

If you put your finger over it and the idle starts behaving then you've found your issue. Sometimes the wax in the waxstat breaks up and that port remains open even when the engine has warmed up.

Hope that makes sense mate.

 

[rid1ridz14]

idle is already behaving right now, it's rough and jumpy..
I'll try that tomorrow and see if there's any difference

Any other proposal on what could be causing this?

 

[Jay]

Failing a fault code being present it's a bit difficult to guess unfortunately. Check the codes when you are checking the air feed port and report back.

 

[rid1ridz14]

Diagnostic port codes? There’s no codes unfortunately when I bridge the two ports

 

[rid1ridz14]

So I what you said and as soon as I put my finger on the port, engine feels like it going to die

 

[rid1ridz14]

Engine warm, put my finger on the hole inside the TB and it stalls. Is that normal for the waxstat?

also here is the symptoms I’m getting
-Burning excessive fuel (smell and sputters from exhaust)
- idle is jumpy and high
-idle screw is all the way in and still idle is around 1200 rpm
-i have new stock injectors in
-stock fpr

 

[Jay]

Try adjusting the idle screw up a bit then do the ole finger test.

(Might have been adjusted in the past and is too low for a regular idle)

 

[rid1ridz14]

as my idle is high I need to adjust to make it less, but it's already all the way in (low idle). If I unscrew it I'll get higher idle than I already have..
if that makes sense

 

[rid1ridz14]

I'm thinking of a few things, maybe my stock fpr is no good anymore, reason being excessive fuel burning.
But can't figure out the the high idle issure.
TPS I tried adjusting and it seemed good.
I have a new air intake temp sensor on
IACV was cleaned

 

[gorganl2000]

is your oxygen sensor working? check its wiring/connection

 

[rid1ridz14]

I remember changing it back in 2020

is there any test I can do to see if it’s working properly or not?

 

[SKINY]

Have you tried adjusting the cable itself yet

 

[rid1ridz14]

throttle cable? No I have not.. but before it was running fine.. you think?

 

[rid1ridz14]

Is the waxstat suppose to make a hissing sound? It’s coming from the port that Jay told me to block off. When I blocked it off, engine dies
Any help please
