Ssang Yong korando 2013, car has only 50k miles, sometimes when driving the car (usually on a cold start) but not necessarly, , to demonstrate it feels like you slammed the car in first gear for half a second , the engine slams and slows down suddenly for about half a second then the car continues normally, I know it sounds like a transmission issue, but the transmission works absolutely fine, as far as I know it seems more of a fuel system problem feels like the fuel suddenly cuts off from the engine, I have used multiple injection and fuel system cleaners in the past and it seems like the problem disappears for a short while or at least occurs less than usual, unfortunately slightly later on the issue starts happening again and goes to it's usual occurrences , which made me certain that it's an issue with the fuel system.
engine air filter is in good condition, car shows no error codes or warnings
It could be the fuel pump, the fuel filter or the injectors, judging by the effect of injection cleaners since the problem goes away then comebacks later, seems to me like a clogged fuel filter what do you guys think?
Hi,
Ssang Yong korando 2013, car has only 50k miles
Oh I remember this car.
You replaced the previous engine? repaired? what's up with that?
I spent sometime researching the 2.0 engine you have,
it's actually the G20DF (Ssangyong wrongly labels it as the G20D which is not true)
And the issue you described is not unique to your car, but it's ultra common (always happens!)
This video describes the issues with the engine in great detail,
Use captions to translate to English.
(Settings -> Captions -> Auto Translate -> English)
to demonstrate it feels like you slammed the car in first gear for half a second , the engine slams and slows down suddenly for about half a second then the car continues normally
Basically the transmission jerks when shifting gear?
Does it happen when you're just cruising in gear?
If this 'leaping' happens when shifting gears, that's probably because of the time it sat without the battery being connected and now it's running on the defaults - perform the adaptive learning procedure (probably will require a scan tool, an ELM327 might be enough although I am not sure)
If it's when cruising in gear, I'd suspect the health of the (replacement?) engine.
Hi!!, I am really glad you remember the car and my previous post, anyways about the timing chain (my earlier post) I took the car to a mechanic I trust there wasn't that much damage to the engine he fixed the engine and the car now runs great even better than before, the engine slamming issue was always there even before the timing chain broke, I was hoping fixing the engine would fix that issue but it didn't, so it didn't get better or worse, it stayed there before and after the timing chain broke and the engine was fixed
What I meant by the car or engine slamming it isn't whatsoever a transmission issue, I used that analogy as an example to help you understand what's happening, it feels like it suddenly slams in first gear, the transmission is good and runs perfectly, I meant it as an example ( it doesn't actually slam into first gear or has anything to do with transmission but feels like it)
Feels like a fuel cycle issue, I was hoping for opinions or what people think about that issue, I am sorry the post wasn't clear enough, I am terrible at explaining things, and again thank you
Does it happen when the car is shifting or just randomly?
Does it have a tendency to happen on a cold / hot engine?
I would say it happens randomly, sometimes happens when flooring the gas pedal, but in most cases randomly
It occurs more on cold engines, still occurs when the engine is hot but much less often than when it's cold
Using injection and fuel cycle cleaners seem to solve the problem for a short period of time, but later on the problem returns
If you're sure it doesn't happen when shifting (which is what I'd expect) - then perhaps inspect the fuel filter and connect an OBD2 all-systems scan tool to see if there are any codes.
I don't have a scan tool myself, I did a scan a a short while ago and it showed no error codes, I have a feeling it's the fuel filter I already ordered one from Ali Express since it's hard to find parts for this car locally, and I have no idea if other fuel filters will work properly, I ordered to be safe, I will shoot my shot with changing the fuel filter and see if the problem is solved
I am positive it's not an issue with the transmission, i can tell by the way the car acts it's something with the fuel cycle and the engine and not the transmission, I know what it feels like when transmission slips, jerks, or shifts weirdly, and this is totally different
So... I know you're trying to avoid the plausibility of the diagnosis being transmission related but, I still would like to know:
Does this happen when the transmission shifts? or only when the transmission is in a gear?
Happens when it's in gear I am positive
