Throttle problem ??


Recommended Posts

My 2015 lsv 247 is bogged down at full throttle with top speeds around 15mph.  When I leave it in mid throttle position for some time driving straight. It will all the sudden become response again and drive normal with full power.  Power or throttle response seems to come and go.  Does this sound like a Throttle position sensor or something else? Appreciate your help.

It could be several things beside the TPS, including bad spark plugs, bad plug wires, distributor cap/rotor, coil, fuel pump, fuel regulator, fuel filter, fuel lines, etc.  Do some diagnosis before you just throw a bag of parts at the problem.  I personally would start with a full tune up, then test the fuel pressure if it still doesn't run correctly.

So right.  I was trying to skip right to the problem without any diagnostics.  I will tune things up and check out TPS with volt meter before moving on.  Thx
