I just replaced the spark plugs on my '05 650 and have been noticing that at low RPMs around town I get a bucking or surging feeling when I am holding a dead constant throttle. Nothing too bad, just feels like I am running over little bumps more or less (the road is flat, so I know its not that). Also, I feel like I am getting more small back fires when I decelerate and sort of a low gurgle at times that sounds like it is just on the verge of being a backfire but doesn't do it. But this just might be my imagination since I am actively listening for it now, but I am like 90% sure I am backfiring a little more now.
My first thought was that it may be a bad gap on the plugs since I didn't have a gap gauge and thought the new ones looked about right, so tonight or tomorrow, I am going to pull the plugs and check the gap to confirm.
The second thing that came up as I was searching was people kept mentioning TPS adjustments might be the problem, but I already adjusted mine at the end of last year, and it was running fine until I changed the plugs. Do you need to readjust the TPS when you change the plugs? sort of makes sense I guess ???
The plugs are the only thing I did that would have changed anything. Is there something else, that may have coincidentally happened at the same time, or that I may have hit while changing the plugs that could cause this problem? Anybody have this issue before and figured out where it was coming from? Thanks in advance! And sorry for the long post.
