QuestionQUESTION: This car runs fine in every way except...At medium or full throttle the engine cuts out and begins to sputter. It seems related to the amount of boost being provided by the turbo. Seems like a timing issue to me. It only happens at about 3000 rpm just as the turbo is about to really kick in. I have tried everything,new TPS, Distributor Pick Up, Fuel pressure regulator. I have checked for timing advance function and set base timing. This used to only happen when the engine got hot. Now it happens all the time. I have also connected a scan tool and checked all sensor functions. I just hope you have seen this problem before.
ANSWER: Hi Ben,
I have not had personal experience with the Turbo. When you say you have connected a scan tool did you verify that it was capable of reading any fault codes? If not, try the ignition key/power loss light method of reading for codes:"on-off-on-off-on and leave on" doing that in 5 seconds or less elapsed time. Then watch the check engine light which remains 'on' to see it begin to flash, pause, flash, etc. Count the number of flashes between each pause. Then repeat to be sure you have an accurate set of flash counts. Then let me know the counts in order of appearance and we can go from there using the manuals that I have.
Another idea would be to ask at a Yahoo.com autos group that I co-moderate as there are many turbo owners who may have experienced this problem. http://autos.groups.yahoo.com/group/thechryslerlebaronclub
where you can search the archive, and join if you would like to post a question.
Best of luck with this.

QUESTION: I did pull codes and got code 54. Have replaced pickup and checked wiring very carefully. Also a lean oxygen code but assumed the two were related
AnswerHi Ben,
The oxygen sensor code is generally not related to a 54 code, particularly if it comes up after you did the pickup servicing. Have you tried erasing the codes by disconnecting the battery for a minute or so and then checking for fresh codes (other than a 12 which will be caused by disconnecting the battery) after driving it for a few trips but avoiding the use of the turbo so as not to cause an abnormal exhaust situation? If you then just get an oxygen sensor code that would be a basis for replacing that sensor. Similarly check its wires carefully as they are very fragile.
