Lambda readings?

trisha

hello

car is Astra 2001 Z22SE
I have erratic idle like shaking like hiccup. sputter on idle.
that all happened after rebuild because of burning oil.

now i have hard start when it's warm and idle problem.
on board computer consumption is 1.5 l/h on idle.

i have cleande TB, changed CTS, cioil pack, spark plugs, cleaned injectors.

here are the readings of O2 sensors:

I guess its easier to record screen with potato than pressing Record button in OP-COM software.

At the moment when you recorded the data, there was ~ 39 °C outside?

trisha

anyone?
crank sensor? is it possible?

Johnss

"Calculated Throttle Position" too high - explains increased fuel consumption.
"EGR Position Feedback" seems to show to low value.
"Ignition Spark Angle" appears to be wrong.
All this of course are needed to be confirmed.

trisha

should I try another throttle bod?
how can I correct ignition spark angle?

Johnss

Yeah, took a closer look.
Throttle Position should be 1% at idle. Yours appears to be shifting in range 9-12%. No idea what cause this. Fault in throttle body? Could try another another throttle body. Idk will it work PnP though..
Anyway any opinions from experts like @[deleted] ?

trisha

Thank you. I vould like his opinion 🙂
I noticed one more thing. When i accelerate and pass 4000 rpm and put in 3rd fear the car feels like no power. All below 4000 is superb changing grar

trisha

this is how butterfly on throttle body works on idle:

and this is how rpm is not steady at 1500 rpm, also you can feel and hear puff puff on exhaust:

i have changed almost everything (TB, CTS, Coil pack, fuel pump, fuel filter, checked chain and put a new tensioner from NET engine)
i haven't changed inlet manifold, crankshaft sensor and fuel pressure regulator.

could it be that FPR is responsible for my starting issue? i have read in this tread that FPR was the problem: https://z22se.co.uk/threads/differences-between-fuel-regulators-on-vectra-b-and-c.25295/
