[MBZ] 2.5DT Idle and turbo issues

2007-09-08 Thread Ralph W
Hello All, I've been following the recent 2.5 threads with some interest. My '90 2.5 has some been very sluggish lately. Limp mode is a bit overstated but I would say I'm not getting any help from the turbo. Mileage on the car is still around 29 MPG. I must also note that I believe I have a

Replace the head gasket (and head if necessary as it may be cracked) or soon you will need to replace the engine. You are both getting coolant into the engine and sharing compression between a couple cylinders -- the rough idle is a combination of low compression knock and flame suppresion

Thanks guys. A little dose of reality from the group is helpful some times. I've had my head in the sand for a while on this head gasket thing. I have had coolant loss and white smoke at idle but the Irontite seems to have stopped that temporarily. My wife won't drive the car due to the loud

Well, first of all, you seem to have a basketcase there. You are going to have to deal with the head gasket issue if you plan on keeping the car. Next, if you have a rough idle, you probably have some bad delivery valves. You will want to loosen each injector line one at at a time to see

yea, all my other info assumed the problem not coming from the head. If it has been going on a while and really is bad, your head is most likely your problem Peter Frederick wrote: Replace the head gasket (and head if necessary as it may be cracked) or soon you will need to replace the

once its warmed up. As for checking the sensors, you will need to read thru the 178 or so page EDS diagnostic to figure that out. Kaleb, I was hoping you'd have that all figured out by now. It has been a few days since that thread. What have you been doing? ;) Ralph W. '83 300CD '82

Well I do have it figured out pretty much, but I doubt my problem is the same as yours. You will still have to pull the codes. On mine I am going to have to replace the IP, the rack sensor is bad. Ralph W wrote: once its warmed up. As for checking the sensors, you will need to read thru
