    2001 DTS - new to me - tune up ?

    I just purchased my second Caddy, a 01 DeVille DTS. Got it from a dealer with 74K. It was too clean to pass up. I got my 99 D'Elegence from a dealer also and pretty much did a full tune-up within 90 days. Spark plugs, plug wires, ignition coils, air filter, and fuel filter. I'm thinking of doing the same with my new DeVille DTS except I'm thinking of holding off on the coils due to cost. Anyone see a benefit to changing the coil now as opposed to waiting. I'm not experiencing any reasons to change it, just looking to give her a tune-up since I don't have a record of it being done recently.

    If it ain't broke, don't fix it. The coils may never fail on you.

    Perfect. Would it be beneficial to change the plug boots?

    Only if you have a misfire because there is a chance that one may be carbon tracked. If it's not missing, personally I see no reason.

    Awesome! Yeah, no issues with anything, just wanting to do a standard tune-up. My 99 had almost no miles on it and had to replace almost everything on it. Is there any other items you might recommend replacing? Thank you for your help also

    The plenum ducts are known to rip on the bottom at the 6:00 position. When that happens you notice a rough idle, the MIL will illuminate and you'll have a P0171 & P0174 code. Also GM had a bad supplier of CKP sensors from 2000-2003. Unless yours have already been replaced, they will also fail at some point. Symptoms will be stalling on deceleration or at idle. Sometimes a longer than normal crank time. They should (but don't always) trip the MIL and store a DTC.

    Oh, yeah, clean the TB. First time may be a bit tedious, but if you do it yearly it's not much more than a spray and wipe.

    Ranger, or anyone else, do you know where to get a replacement fastener for the trunk floor linear, or what it would be called to search. Pretty silly design if I say so. I may try a pick and pull yard but would rather have it mailed to my home.

    Dealer, ebay, or salvage yard (where it would probable be free).

    Fastenal stores carry a bewildering assortment of automotive trim and panel fasteners.

    The floor liner is held down with screw on retainers that are also the anchor points for the cargo net. They're a specialty item.

    I am one who thinks " If not broke, don't mess with it" If you find you have a little roughest, change the rubber boot at the throttle body and the plenum. I found that was the whole problem with my 02. It is only 40 at the dealer.

    If you have trouble finding the hold downs, I have several. Not sure if they are exactly the same as yours. I think the came from a Seville, but might be the same.

    Thanks Ranger!! I'll let you know if I can't find any. So far I've replaced the air filter only. Put in a K&N replacement filter. Going to replace the fuel filter eventually, just need to jack her up for it. Stopped by my dealer last week, he checked the service and the CKP sensors have already been replaced, as well as the half case gasket!
    I just assumed I didn't see oil because it was cleaned before I bought it.

    Do you know if the fuel pressure regulators need replaced in the 01's often? I did it to my '99 and it was simple, just a little difficult finding the right one.

    The K&N filter flows more dirt, and packs up 3 times as fast as a standard paper filter. And a paper filter flows more air than the engine can use at WOT, at redline. I'd suggest returning it.

    The FPR is as reliable on an '01 as any other year.
