Help diagnosing issue with Renault Clio IV 0.9T

[JacquesRamsden]

Hi petrol heads,

Here's a puzzle for you!


So... I did an oil change. Yea a straight forward oil change. Plug out, oil filter cap off. New oil filter cartridge, plug back. Filled with oil... Eazy peasy right.. wrong....


Now the car shudders when revved over 1500rpm. The only think I can find is that the iat sensor reads -40c which is obviously wrong. But... I replaced it (with a second hand one), chances that both are broken are very unlikely. I have back probed all the wires and made sure the open circuit voltages are correct. I double checked the other MAP sensor (the pressure one) and that's fine.


All other readings on the ODB are good except for the spark advance that sits at -30 ish during idle but I will be honest I'm not sure on the normal reading for the advance on this car.

Any help would be appreciated.

What do you mean by shudder?
Is it automatic or manual?

Manual, so it's weird and hard to explain, the car does not make a noise it just shakes not violently but you can feel it's not running a smoothly. It's 100% not engine mountings those are secure
