So my recently new to me truck truned on the cel last week. Came up as a P0089 which is fuel regulator performance. Cleared it, and it returned later that night. I did some searching and investigating today. Most of the diesel forum guys coincide this with a surging idle, comparable to a big cam in a gas engine. If anything I noticed a very slight occassional stumble at idle while wating at stoplights. I never thought too much of it until the CEL came on. Looks like sawpping the regulator out is a little over $200 in parts (bosch) and anywhere from 3-8 hrs of my time.
I was curious about the location and cost of that pressure sensor, since I'm not noticing a big driveability problem. There is also a bulletin about some bad terminals on that plug as well. Anyone been through this? I hate to spend the $200 and more importantly time chasing down a gremlin.
