I'm new here, but I do know enough to be dangerous. I read a few posts about running problems with no engine codes. I was wondering if anyone had herd about the ground on the front side of the engine, down around the front engine mount causing problems. I'm no expert, but was told about it on 4.5 Deville that ran bad after new plugs, wires, cap, rotor, coil, and I can't remeber what all else. This car blew the muffler apart from backfiring. I can't remember what all else, but do remember that. Seems like it had a 15mm nut, then a double sided stud. All I did was take everything apart and clean it so it had a good connection, and that fixed it. Some thing about the bolt being steal, the block being alm, and the connector being copper made them oxidize over time and not make a good connection. Just throwing that out there. Thoght it might be helpful to somebody, and was wondering if anyone else had heard of anything like that before. One other question. Every once in a while my 95 Eldo will set a PO39 torque converter clutch code. I would say "random" but I can almost make it set the code. The TCC solenoid has been replaced, and it seems that it only does it with real light load, like 45 mph in 4 gear. Do you all think a rebuilt converter will make the code go away? Car has 112,XXX miles.
