I've been jumping into other folks' threads and venting and I apologize for that. Best to provide an update on my own thread - lol.
Long story short, our 4010 was just brought back to us this past Thursday after giving the dealer a call on March 04 with there RPMs dropping. Part of the time was them getting out to pick it up (I really need to buy a trailer), 2nd part of that was they are simply slammed with work so it sat, and the 3rd part is the issue found ended up with them have to order a part that was on back order.
After hooking it up to the 'puter and calling Kioti a couple of times, they found the EGR valve cooler was leaking water into the injectors. They ordered (backorder) a new cooler and got it replaced. Let it run a few hours and brought it back to me on Thursday. I hopped on it Saturday and mowed for about an hour and a half when suddenly it started doing the exact same thing (mowing at about 2000 RPMs and it would drop to about 1000 RPMs, idle at that for 10 seconds or so and shoot back up to 2000). It did this 4 times over the next 15 minutes so I parked it.
Needless to say I was standing at the door of my dealer when he arrived this morning at 7:50! Actually his mechanic got there first and we discussed. He did own up to the fact Kioti had told him there might be a slight chance the injectors were damaged due to the water, but none of his tests and it not happening when they ran it (plus us being without it for almost 2 months) led them to bring it back out to us. They are thinking now that the injectors need to be replaced. The mechanic was pretty adamant even to the owner that they needed to get it picked up today so he could start looking into it and get necessary part(s) ordered. Owner of course pulled out the list of "this is due, this is due, this is next, etc" but did say he hoped to pick it up today.
I trust my dealer and they told me they have sold dozens of the 4010 and have had zero complaints. I'm just the lucky one! lol
Thanks for reading!
