Message: [QUOTE="TARM, post: 1036534, member: 578"] Is this something that just started to happen all of a sudden and all these symptoms at once or has it come on more gradually or in parts in terms of the various symptoms? Did you run a contribution test as that will show whats going on with balance between each cylinder and thus look at not only the CPS readings but if compression and valve seal is fairly consistent will show injector balance. I would switch to a Delphi or BW CPS so you can be sure of what you are seeing in terms of cylinder balance on the perdels. That stumbling and almost dieing can sure be bad CPS which can go bad at any time. Check the end of the CPS when you pull it to see if there is any wear on the end probe/magnet end. The high EGT and black smoke could be a boost or up pipe leak. 26 PSI seems very high for a stock turbo to last as well as not have high EGTs. Unplug the ICP sensor and see if the idle changes. Look for oil in the plug. Was the ICP you replaced it with ford/IH or aftermarket? The bad idle when warm could be worn injector or its orings issue. When you said IPR/ICP numbers look good what are they and what conditions did you check them in and compare to? With AE log the ICP IPR numbers pressure % volts when cold and fully warm (where the idle changes to poor) and report back. Check your oil dip stick also cold and fully warm.
