Default Watch my video and tell me what's wrong? (HPI RS4)

Yes I am new so please excuse my driving

I can't get full throttle, it seems like engine will die

I tried richening and leaning both didn't seem to do any difference

any advise?

Lots of smoke so doesn't seem to be lean. Might be an air leak somewhere. Check your tank, lines and exhaust coupler.

I did replace my tank because of a wild accident but the 2 hoses I did not replace..
How do I detect/test for an air leak??

Someone made a comment on Youtube about Exhaust coupler (Thank you whoever you are) and yes I am missing 1 zip tie. I broke the other one and didn't bother on replacing it. I will try that tonight! That could be it!

also., these are old videos but watch and listen to the sound of the engine and how the truck behaves after each setting.

I fixed the problem. It was the Exhaust coupler. I added a zip tie and also i found a trick

Instead of pressing the throttle all the way, I tap the throttle, after a few taps, my car would have no problem after pressing steadily.

After fixing the problem, of course a new problem came. The car was able to accelerate fast, it was too fast I lost control and hit my own toolbox (I was driving too close) when I was doing a passby.
Now I broke my front bumper and front tire. That is okay, I fixed that before. I am happy, I fixed the issue with the engine =D

Glad you got it all sorted out. I'm the one who posted on your video in YouTube. The motor was blowing plenty of smoke so it had to be a leak.
