#2470 of 2506 Re: Additives to fuel stystem [onelord] by bremertong Jun 30, 2008 (10:19 pm)
Replying to: onelord (Jun 30, 2008 8:28 pm) I owned a 1998 Deville and later a 2004 Deville for three years each and always used STP fuel injector cleaner fluid with each fill up. never had any problems. The 98 got about 27 MPG highway and around 20 in town. The 2004 around 29 MPG highway and 21 city. You may have other issues and may want to try a complete fuel system cleaner (STP has one as do other additive companies). Have you checked your air filter or replaced recently. Your MPG stats sound low so you may want to investigate further if my two suggestions don't improve your MPG performance. The 98 Deville had 39,000 miles on it at time of trade and the 2004 Deville had 36,000 miles on it. Both much lower mile cars than yours but still think you should be getting better results.

Replying to: onelord (Jun 30, 2008 8:28 pm) Unless you have been using very cheap unbranded gasoline, I wouldn't think you have injector problems.   With that milage, i woujld be thinking about plug wires and plugs. Us only GM wires and the recommended plugs. The wires and plugs should be good up to 100,000, but expecially if you have had some mechanical work done near the wires, they could be messed up. If you live in extremely hot area, the wires might also have broked down early.

I was thinking of using a good brand of injector cleaner. I dont think its the plugss the car runs smooth and has great getup. I think it just needs some injector cleaner. Thanks for the info from both of you. Any info will help all of us. Replies to this message: bremertong (Jul 02, 2008 8:52 pm)

I have not had any slipping or noise or problems with my transmission until today. While driving on the highway I lost it suddenly. It will only go into first gear. Will not reverse either. Any ideas? Bob
#2478 of 2506 Add Bluetooth to a 1992 Deville? by jeffwilson Oct 17, 2008 (10:49 am)
I am buying a used 1992 Sedan Deville w/46k miles. I want to replace the stock stereo with one that has Bluetooth and an iPod interface. Has anyone here done something like that? Can you suggest a model that would fir the car and if a new wiring harness is needed? Thanks very much in advance.
#2479 of 2506 Alternator running high by caddyshaker Nov 02, 2008 (11:31 am)
I'm new to Cadillac and don't have a whole lot of experience in mechanics....Can tear a car apart, but can't do diagnostics. I just purchased a 91 Deville Sedan that had an old battery in it. I drove it for a day, parked it and over night the battery was drained. Got it jumpstarted the next day, ran for the full day shutting it off and turning it on, went to Les Schwab because I'd picked up a roofing tack in my tire and needed it fixed. The battery was smelling like sulfur and they replaced it. Schwab tested the Alternator and said that it was running on the high side, but nothing that would cause a battery to explode. I've been pulling the cable at night to keep the battery from being drained. I noticed that someone has cut the wires to the battery and put a new terminal connector on it. There are three wires hooked into the positive and just one on the negative. I've been trying to get schematics to see if this is accurate or if someone has possibly put a negative wire on the positive post. Also i get a service air conditioner light, but was told not to worry about this when i'm driving it and these lights come on, it comes on with the coolant temp fan light and service soon light......sometimes it acts like the fan is trying to turn on and breifly acts like it's draining the battery.....i know it needs a tune up.......i got it from a parts and sales wrecking yard fairly dirt cheap.
