Missfire cyl 2, intermitent eml , check esp, check injection, limp mode, exhaust popping at iddle

[Juanaan98]

Well, thats everything my clio has, it's blowing my mind how many things went wrong for de 5 months I have owned the car, changed aircon compressor, alternator, the pulley from the camshaft... and list goes on..

These are the new problems (but surely not the last)

So when the car is running for sometime, check engine light comes on, intermitent and goes off (sometimes), sometimes it throw error check esp, check injection and goes into limp mode (sometimes also stop and turn off by itself) but when I turn off and on again the car, all the problems are gone.

I have noticed that the exhaust pops at idle (that isnt very normal I think).

I have change all four coils, and lambda sensors, which many people told me that those symptoms are from those components, no luck.
Spark plugs has less than 500 miles son I think that wouldnt be the problem either.

When I plug the obd, it throw me missfire in cyl 2, I dont know if the problem are the injector or maybe the cyl compression.

If someone can help I will be really, I mean really grateful.

(Sorry for my bad english, Im from Spain)

Did you get sorted? I’m having similar problems! From what you’ve said I’d start by cleaning the electrical contacts to coils, maybe injectors, crank position sensor and camshaft position sensor. I’ve not sorted mine - going to replace my coils and the 2 position sensors…

Update on the issue:

- The engine was on the brink of blowing up, and I had to replace the engine block, pistons, and crankshaft because the oil nozzles were not spraying properly, and the engine was nearly seized. Luckily, the low oil pressure light came on just in time. I'm working on it and taking the opportunity to replace some other parts. I haven't taken the car out on the road to test it yet, so I don't know if the issue I mentioned earlier has been resolved.

If the problem persists, what should I look into? I've read that it could be the pedal potentiometer or the throttle body. Most of the times when the car went into limp mode, it was during steady speeds, and the intermittent engine fault light, injection check, and ESP light would come on (I THINK THIS IS WHAT YOU REFER TO AS "LIMP MODE"). Any ideas? (Although I hope it's resolved by the time I finish working on it).
