172 cuts out at low RPM

[Luca.smr125]

Hello, my 172 ph2 is cutting out when im driving away from a stop or when im driving out of a hairpin turn at 2nd gear. It doesent happen all the time tho.

My father pointed out that it could be a faulty Lambda sensor or that the engine needs some run time again because it was stationary for 4 Years.

It only accurs when the engine gets below 2000 RPM and dissapears after that. I dont think that its a lambda because it feels more like a ignition problem. Im looking forward to order some Coils, Cabels and new Plugs and if it doesent dissapear then continue the search.

Have you checked the air filter area too? All clean and not clogged?

Could be the MAP sensor. Is it secure against the manifold? may even be worth trying that first.

If there's no misfire, throwing money at ignition related items seems a waste. I may be wrong.

Yes the airfilter is fine

You can hear it abit from the exhaust. But the Plugs, Coilpack and the Wires look fine. Im gonna take apart it more and see if i can reach the MAP sensor

Have you tried the PAS sensor, can cause it to cutout at low rpm, when idling and stationary turn the steering side to side, rpm should go up.

Yes when i turn the steering wheel the rpm needle moves. Its the pas sensor from the gas?

Was there fuel within the car when you left it to sit for 4 years ?

I think not. When i picked it up the tank was allmost empty.

Try getting some decent fuel through it , super unleaded. Then clean the sensors up. You can get to the main ones no problem. Happy to take a pick under my bonnet tomorrow if you get stuck.

Also check your throttle body butterfly. The opening and closing part. Make sure it'd not sticking and give it a clean.

I got like 2-3 Tanks of 98 RON trough it now. But then i try to clean the sensors. Just the one that i can reach or also other ones?

I'll grab a photo of what I would clean.
