Jerky acceleration low revs

[Hawwy]

How would i know if the valve is okay?

 

[5e colin]

suck and blow on it clean the pipe first coz it rotten

 

[Hawwy]

Not sure if i will be able to get valve out without breaking it

 

[Fez]

The rubber grommet might have gone brittle and break off. The valve itself should be alright. Better have a grommet standby just in case

Also it does this

Then straight after does this

you definitely have a vacuum leak somewhere
check all those vacuum hoses as well

did the map sensor code come back?

 

[Hawwy]

If you mean the code in the video, no it didnt.

 

[Hawwy]

The error code has come back when doing diagnostic

 

[dac69er]

either a vacuum leak between manifold and map sensor, knackered map sensr, a wiring issue or emanage has died.

i would suspect a leak or wiring issue.

 

[Hawwy]

Even when car is off, after a while like after every 5 mins it makes a buzzing noise from coil/ignitor, dont know if its related to this?

And the hunting idle doesnt happen all time, only sometimes

 

[gorganl2000]

do you have any starlet/glanza friends close by?....maybe try their map sensor IF it has the same part number
i had a similar "hesitation" experience in the past when my map sensor was bad

you sure its that and not the carbon canister? that makes a buzzing sound. can you remove your emanage and just run the standard ecu or is it spliced into the main loom?

 

[Hawwy]

Im not too sure how its wired

But if it was the emu then wouldnt it fuel cut?

Also the map sensor is it the standard one or the greddy one?

And the buzzing it sound like its from coil i dont know where the carbon cannistor is so im not sure but every so often randomly i hear buzzes.


Today in morning car was really rough first start for a min then the roughness went, and the jerkyness has gone better since replacing pipe from inlet to pcv

 

[dac69er]

not necessarily, electronics do random things sometimes.

the carbon canister is just below where the coil is.

 

[gorganl2000]

most likely the canister near the fuel filter that is buzzing....does it ever so often, even when the car is off
