Hello guys, so recently I bought a 2009 I30 2.0 and I started to notice this weird problem.
Basically when I accelerate slowly the engine kinda stalls randomly, like for example the rpm would drop down from 2000rpm to a 1000 or sometimes less for a second then all comes back to normal again, I changed the camshaft position sensor twice (both times according to the computer it was bad) and it has another error which is related to the immobilizer transponder error (Idk if that is relevant to the problem).
I've basically changed the fuel filter, water pump, sparkplugs, sparkplug wires, air filter, timing belt.
The problem is getting annoying as no specialist is able to put a finger on the exact cause of the problem, any help?

SO, not a lot of info so far then...

Perhaps to clear all codes, and wait till it does it again and read the code and post . Codes will only present with a final outcome, provided by a sensor and may not be the "actual issue"  as you already know, but with the specific code number and detail, there may be some more ideas from others.

Sounds to me like a coil breaking down intermittently, but only another guess.
