Well, these last 6 days have been a time to remember. Over the past year I have asked Case numerous times to check out the engine in the 210. I felt that there was an injector that was not 100%. The first time they checked it, a year ago last summer, they tried to bill us over $400 to run the injector cut-out because the mechanic claimed he couldn't find anything. I told them what they could do with that bill, and they backed off. This summer, I had an issue with the bucket closing, and while they were there I inquired again about the engine running a little rough. That mechanic also was unable to determine if anything was amiss. So, I'm working last Tuesday, and finally the problem seemed to be getting worse. Wednesday, it definitely was. Called Titan, guy came out on Thursday, he determined number 4 cylinder was not firing. I was there during his tests, and told him I also felt number 3 was trouble as well, he disagreed and said he would get A injector. As it turned out, injectors were back-ordered (shocker), and the closest one was in Sioux Falls, would take 3-4 days to get. I told him that I had been complaining about this for over a year, and that injector better be in Bismarck in the morning. It wasn't, supposedly because of the snow, so he brought it out yesterday and changed out number 4. Started it up, and what do you know, still had a slight shudder. After some more investigating, he "determined" number 3 was faulty. No $hit, Sherlock. After some pretty tense discussion where he asked me several times if I really had had 2 other mechanics check it out before and both claim nothing wrong, he said he would do his best to get an injector ASAP. So, when he leaves, he says he will call me as soon as he knows something in the morning. This morning, he calls at 8:05 and says he has an injector (???????) and is on his way up. Put the injector in, and engine runs like a brand new one. 6 lost days this time of year to a problem that should have been fixed LONG ago is not good for a man's frame of mind.
