Year, make and model. Engine size and specs also. Carburated/fuel injected? Give the basics first, and Im sure some can help you. Its either electical or fuel related, but after a tune up, must be electrical. Check connections and sensor connections. Sounds like spark or timing.
As college man asked…..what tuning did u do? Name it all. at high RPMs, it can be a lot of different things. IF it only happens are very High RPms, then it is spark or fuel related. Only driving it, could I tell.
But,,,…if u did tune up and now its happening, must be something u did in tune up.
You have to trace all of it down the to gap on your spark plugs. But either fuel is not keeping up or your coil is poooping out. Not to mention, if any of your sensors are not responding properly. To make it more confusing, all this can affect your timing.Sorry for the confusion, but like I said earlier, it can be as simple as a bad connection to all of one of the things mentioned above. You might have to take it to a tech so he can diagnose it for you.
Sorry I couldnt be more help.
Good luck and let us know if you find the problem.I’m going to shoot the next person that says put a TPS on a vehicle because it has a hesitation problem, especially a Honda!
What ‘tuning’ have you done? Just because you said that word I would suspect it’s something that’s been done to ‘tune’ the engine so look over that work as it may be the cause of the problem.
