Guys, I'm having a strange problem in my car: it randomly

>>16520989
needs a new spark belt for sure

>>16521064
You mean the timing belt?
BTW, forgot to mention it started happening some time after I loaded some fuel in a neighboring country

>>16520989
sounds like either timing, or old plugs/wires

>>16521077
I was memeing, >>16521152 is probably on it with the spark plugs. Pull em and check them out.

>>16520989
Start with plugs & wires, check your idle control valve, any check engine lights?

>>16521077
>>16521165
Also, remember that spark plug cables are consumable and wear out just like anything else.

>>16521165
>I was memeing
oh lol
>>16521152
>>16521166
>>16521169
I'll do that, thanks guys. Also no check engine lights.

>>16520989

crank shaft or cam shaft sensor

>>16520989
idle controll valve is dirty....

>>16520989
Could be the fuel filter if you put on fuel that might be filled with shit. Also depends on when you last changed it. EGR valve is also a good idea to check.

>>16522158
It's a manuel
>>16522234
ouch
>>16522271
It was on 1/4, I filled the tank with shitty fuel, when it was back to 1/4 it started giving me issues again. I filled to 3/4 with good fuel and then when it was back at 1/4 I loaded some premium fuel.

>>16520989
if it has a lot of miles you probably just need to clean the throttle body.

>>16523129
ect = engine coolant temp. Stop wasting money on premium gas unless it's required in the owner's manual.

it could be a vacuum leak.

Well I went to my mechanic and he told me to put some injector cleaner additive, let's see if it solves itself. I didn't pull the plugs out because I lack the necessary tools (it even has a cover with torx screws)

Seafom.

Here's what you do anon.
>Put in fresh oem spark plugs
>Coil packs are going bad, replace all
If no coil packs, replace the spark plug leads with high quality ones like NGK, Bosch or whatever.

Check for fault codes. If there are any relating to mixture adaptation limits being reached then it's probably a fuel delivery issue. In that case check the pump (and filter as others have said).

An update guys: I found out that engine braking tends to trigger the issue. I've been driving on the highway for the last hour and it gave me the problem most often after stopping for the traffic lights.

>>16525033
Injector cleaner is a meme unless the car has literally never seen one in its life. The additives in fuel are more than enough to get rid of carbon buildup on the inside of an engine.

>>16529049
Typical additives prevent buildup. But nothing is very effective against existing deposits.

>>16529049
What about gunk buildup tho?
