Peugeot 206 14i lx 2002 petrol erratic(mostly low revs) idling and lost of power sound like blown exhaust almost cuts out with foot off accel, oil on one spark plug no smoke white or blue

Your Jeep is Burning Oil. Do you need a Quart every Now and Then? The only way to fix this is to get the Piston Rings Replaced and is not Cheap. There are a Few Additives on the Market that you can put in the Motor to Minimise the Problem for a While. You need to go to Your Auto Parts Store and see what is available in your Area on these though. Please Rate My Response! Thanks!

spark plug gaps are very critical on computerised cars!! [some wont even start!]
distributor module may be breeaking down as temp rises they fail!
otherwise do compression check as it may have valve problems
also check plug leads & injectors aswell as the fuel pump pressure [ could bestarving for fuel]

Probably valve cover gasket. This oil does not affect operation other than to smoke a bit. Idle and power issues are unrelated to oil. Unless it is missing, power and idle may be fuel mixture issue. Is the engine light on? If yes, get a scan at autozone or advance and report the codes to us. If no engine light, clean throttle plate and airflow sensor with carb or electric parts cleaner. Clean any other parts that have gas flow, such as PCV and EGR valves. Let me know if you have more questions.

Hi, What causes a cylinder to misfire? Basically, it's one of three things: loss of spark; the air/fuel mixture is too far out of balance to ignite; or loss of compression. Loss of spark includes anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. Causes include worn, fouled or damaged spark plugs, bad spark plug wires or even a cracked distributor cap. A weak coil or excessive rotor gas inside a distributor would affect all cylinders, not just a single cylinder.

If you find a P0300 random misfire code, it means the misfire is random and is moving around from cylinder to cylinder. The cause here would likely be something that upsets the engine's air/fuel mixture, such as a major vacuum leak, a leaky EGR valve or unusually low fuel pressure (weak pump or faulty pressure regulator).

In the case of a steady misfire, isolating the misfiring cylinder is the first step in diagnosing the problem. The old-fashioned method for finding a weak cylinder is to temporarily disconnect each of the spark plug wires, one at a time, while the engine is idling. When there's no change in the idle speed, then you have pinpointed the weak cylinder.
A power balance test will tell you the same thing, but this requires some hookups and an engine analyzer. A power balance test is preferable to pulling plug wires, because it keeps you away from the voltage and prevents the voltage from causing any damage to the electronics in the ignition system.
When a plug wire is physically disconnected from a spark plug, the high voltage surge from the coil cannot follow its normal path to ground through the plug wire and spark plug, so it passes back through the coil. Most ignition systems are robust enough to withstand such voltage backups intermittently but not on a prolonged basis. If the coil or ignition module is already weak, it may push the component over the brink causing it to fail.
