If I would increase the idle a little it would go off and I could go back to work. I decided to try a new psi sensor, now it seems to go on the same way but increasing the rpm's does not make it go out anymore. When I bought the machine the previous owner told me he replaced the turbo. Is it possible that there is a problem related to the turbo changeout that I am overlooking. Is it possible the oil filter is plugging up? Previous owner changed the oil between the time I bought machine and took delivery. I thought that was odd that he would just up and change the oil but now I think he knew it had this problem. Any suggestions or comments would be greatly appreciated. Machine has the oil cooled Duetz 73hp engine, 2002 vintage.</p></blockquote><p></p>
