sorry sorry, never been to WM b4. im din step out of sarawak not even one step all my life... T_T

wtf man. i got FC issues now. RM50 not even 150km already left one bar...
T_T help. Is it because I ever floor my car before and the carb went psycho? How to solve?

thanks fleek! I'll do that after my final exams! mind tell me roughly will cost how much?

As I mentioned it before, my car's carb got issues.
I haven't go check nor retune yet (cuz final exam now lah)
So I wanna try to diagnose as much as possible myself, with the help of all the sifu-sifu here lah of cos.

So lemme get this straight, before I got this problem, I was running RON97 V-Power. Then I go for EON to do the 35000km service and timing belt change (car is second hand '04 LMST n-line). The mech there got adjust my carb abit lah, I think he mentioned something about the idling too low, causing the car shaking, so he make it abit smoother lor. Ok after that so far so good lah. (i could be wrong, cuz im not very well-versed in malay, and he speaks kinda fast )

Then I still continue use RON97 cuz heard stories about RON95 will cause engine knock and bla bla bla (I was dumb I know). Then when RON97 increase to RM2.9/liter, i started pumping RON95extra from petronas, no issues so far (RM30 can go about 200+km). Then one night, my buntut gatal lor, go play drag race with my friend's BLM (i mentioned this before also ) Then problem liaw. I don't know why or how, just because I floored the car that one time, make my car's FC increase like hell (RM50 RON95xtra go for 150+km left 1 bar of fuel).

I asked before, and Fleek suggest me go retune my carb, but can I know what can I do in the mean time? Can I retify this myself? And what is the cause of this? I really want to know to avoid history from repeating again. I have little to no knowledge on mechanics (i learn about car's parts from video games, youtube videos, speedhunters, and uni textbook). I've tried ask a parts dealer about my problem and he says its because of my engine oil and spark plug (which i dont think this is the issue right now, cuz I've just went for service like 1-2months ago, and I think he just want to earn money from me so i dun give a damn about this).

Lastly, thanks for reading this long post. Sorry for being a noob here, but I am willing to learn! TQ.

Oh and my engine after the service, idles around 900 to 1000+rpm with aircon on, and 1000-1100+rpm when aircon off. During engine autochoking, about 1300+rpm.

Thanks again. Peace.
