Cadillac Jim Posted July 7, 2007 Report Share Posted July 7, 2007 Sounds like a wiring problem between the ignition module and the crank sensors. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

MAC Posted July 16, 2007 Author Report Share Posted July 16, 2007 I swapped ignition control modules out of my Eldorados. The ICM in my silver Eldo works perfect as the engine runs flawlessly, even with over 227K miles. So I installed it in my recently purchased Eldo and still have some erratic idling at times which, if bad enough, will set the P025 and P023 codes. It also sets off a bunch of other codes like a chain reaction. I'm beginning to think it may be PCM related or a bad crank position sensor. I'll buy a new crank sensor first and see what happens.

MAC Posted July 17, 2007 Author Report Share Posted July 17, 2007 I just ordered a crank position sensor. I'll post the results as soon as possible. Link to comment Share on other sites More sharing options...
