jlinde Posted April 16, 2004 Report Share Posted April 16, 2004 Hi, I live in Sweden and my Eldorado TC is a low mileage one (42000 miles)and it has the nice 97-99 chrome rims (from Cardiodoc) with Goodyear Eagle NCT5 - German made W-marked for 270 km per hour. I have got advices from Bbobynski and I did the EGR cleaning - I changed plugs and wires -I disconnected the EGR - I had help from guys who did the instrument checking - no errors or codes except for maybe a little rich on the rear oxygen sensor - so I was adviced to put in some injector cleaner (at full tank etc). None of these things have helped - the car still has a light chuggle or a feeling of ignition miss or too little fuel around 2000-3000 rpm's- any gear. Even the radio reception is disturbed when engine is running - I did put the extra trunk ground wire to it according to the service manuals. The idle is perfect and it accelerates just beatiful and the mileage is as expected I believe around 22 mpg mixed driving. I have a remanufactured PCM (Delco from Coral Cadillac in FT. Lauderdale) which I plan to put in just to test. I also have some ideas to buy a new Ignition Control Module and a Coil to play around with. When down in Florida I also tried to get some ideas from the Cadillac mechanics - one of them said that he had had some problems with one or two ignition modules. For the moment I am studying the manual to see or try to understand what can be checked via the CCC. The manual talks about snapshots etc.- have any of all you experienced guys used those methods??

jlinde Posted April 19, 2004 Author Report Share Posted April 19, 2004 Thank you bbobynski for all the advices on this chuggle thing. I just tested driving the car without EGR connected and I still got te same slight miss which is felt in all gears even without the TCC engaged but I must say that it is more evident with the TCC engaged above 50 miles per hour. During the weekend I changed PCM and followed the manual. The car behaves exactly the same as before. I am glad I put in the remanufactured PCM because then I know it works and then I can have the original as a spare part with me as Sweden is not full of Cadillac service places. The chuggle is not severe at all though - for instance my wife doesn't notice it at all but I will continue to change some parts.... at least it means that I am ending up with spare parts to keep the car running for a long time.
