#1: 206 1.4 Auto rough idle and power loss Author: TigerHunters, Posted: Wed Dec 10, 2025 8:05 pm ---- Hey guys, I have a 1.4 petrol automatic with a few issues.
Full destination of the car type I believe: Peugeot 206 1.4 8v S 3dr (a/c) 2005
Description of issue:
Issues been there since I've owned the car (about 8 months now)
When start the car or the car comes to a stop at idle after a very short period of time the car will start to have a tough idle (like chugging) at which point when I apply the accelerator the car feels as if it's not really responding to the accelorator.
It revs a bit but even with my foot to the floor it will delay power to the engine and then suddenly shoot up and then things will slowly work out and it will seem ok for a while.
I originally thought this was ECU based as coincidently if I restarted the engine it pushed the issue out of the way faster but as I've seen recently it doesn't seem to be the case.
What has been done to try to fix this to date:
Throttle body complete clean out along with attached sensors/IAFV.
Spark plugs cleaned and general checks for damaged wires from ECU (none that I can find)
Also no air flow leaks as far as I'm aware.
Also on basic and advanced diagnostic tools no errors showing up.
Any recommendations what could be causing this?
Please see below (more hear the vid) of the sound of the issue when it happens:

If that doesn't help, replace the coil pack. I had this exact issue a few years back, it was the coil pack. I also didn't have a check engine light come up.
