It could be a few things, but my guess is a fouled spark plug. This could also be a sign of a bad ignition coil, clogged air filter or something wrong with the air sensor, or a major issue like a leaky head gasket. Start with the easy stuff like the air filter and the spark plugs. Also, try to borrow or pay someone to read the fault coded with a VAG-COM, at the very least it will tell you which cylinder is misfiring.

Check for any air leaks on the inlet system.these models uses quite a few small rubber vacuum hoses for various functions like manifold flaps, fuel pressure regulator and turbo actuator and dump valve. any air that is sucked in by the engine after the airmass meter is known as false or unmeasured air, resulting in a lean mixture at low revs. get some carb cleaner and spray it all over the inlet system and injector seals while the car is running.if there is a leak, the idling speed will change when it sucks in the carb cleaner.

Check the coils, there may be a bad coil. That lets moisture in it, and causes the engine to mis fire. God-Bless! Its worth a try!

Peugeot 206 1.4lx 2001 mis-firing and idiling eractically


Hello
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

Very weird, a bad cat should not make it mis-fire, if it is just one cylinder it is mis-firing on, its worth checking the coil pack for that cylinder
