Hi I have a 98 Lesabre with 120k on it. Recently the check engine light came on and started flashing. I took it to advance auto where it was tested and it came back misfire on cylinder 4. I decided to get a new set of spark plugs and change them. I found out it had the original plugs in it. It runs alot better and the check engine light has went off, however, it still hesitates on acceleration and sometimes jerks around 55 mph. I don't think that the problem has been completley solved although it runs alot better. The wires look fine. Could it be the high voltage distributor caps? Any ideas on what I should check? Any info would be greatly appreciated. ~Greg

Replace with AC or Belden OEM quality wires--NAPA has AAA discount if you choose Beldne, e.g. Most likely the wires' resistances are high because the carbon layer has deteriorated with age and use. Putting new plugs in helped but the system is still marginal. Running plugs and wires long also is said to deteriorate the coils. But change the wires first. The coils are best checked by comparing the resistances of the high voltage side where the wires plug in. To compare the primary side, you take each coil off, insert something to make contact internally to measure the resistance. Then clean and coat the prongs that the coil sits down onto. Coat with dielectric grease. BTW, put dielectric grease on the inside of the new wires when putting them onto the spark plugs; it makes them easier to remove. |

Hi - I'm scratching my head on this one so any insight is appreciated! I have a 94 LeSabre with just 44k miles. The drivers side rear door will lock using both the power door locks and the remote keyless entry, however it won't UNLOCK this door using either of them. The other 3 doors work fine. The PDL motor obviously works since it is locking the door, but what can cause it not unlock it only? Thanks!!

I am thinking about purchasing a "backup car". A used LeSabre would be good, if it turned out to be a reasonably low-maintenance vehicle. I previously had its relative, 1999 Pontiac Bonneville, which I bought new and traded in, at the 67K miles, for a new Chevy Malibu in 2005 -- the change I've been extremely happy about. And I wouldn't buy another Bonneville, no, thank you. I've researched multiple user reviews for LeSabre, and have mixed feelings, but am thinking about exploring it further. I'd like to hear any feedback on this, but, specifically, I wonder what is the highest mileage on a used LeSabre, which makes sense to consider. E.g. I see a new listing for a 2002 LeSabre Limited with 97.5K miles -- how silly would it be to buy that car, with that mileage? What maintenance is expected to be performed at 100K? How much money I should expect to invest in the car over the next 50K miles? Thank you for any input.

Replying to: malexbu (Jul 22, 2009 9:12 am) much money I should expect to invest in the car over the next 50K If the owner did good maintenance on it, it's had the coolant changed a couple of times, it's had at least one trans drain and filter replacement, it's had plugs and wires replaced with Delco Plugs and OEM type wires, and news brakes all around. I'd say you're lookiing at less cost than for a high line Accord or Camry.

Replying to: imidazol97 (Jul 22, 2009 10:47 am) I've noticed many messages from you with good technical information, so your advice is much appreciated. Let me put it differently now: if I take your list and make sure that everything you listed have been done (from the information I have, this car has been very well cared for) -- should I be afraid of 98K miles? Is it much worse than, say, 50K? From my experience with Bonneville, I want to think that 60K or 100K don't make much difference -- most bad things happened to me before 50K; and nasty annoyances like broken external door handles ($300), broken trunk spring ($200), water leak through the heater ($500), broken sun roof (left it with that), engine shutoff on the road, don't appear to be directly related to the mileage, but what do you think about this? Would you remove a car with this kind of mileage from your consideration, or it wouldn't bother you much? Thanks again.

Replying to: malexbu (Jul 22, 2009 11:36 am) your consideration, or it wouldn't bother you much? Nope. A neighbor up the road has bought and sold used 3800s equipped vehicles with 200K + on them running well and promising for an economical car. He does low price range cars as a hobby buying and selling; his father has always been in the used car business. The only pattern problem on the car you mention is due to neglect, in my opinion, by not changing antifreeze every two years. If it still has DexCool in it and the reservoir tank looks clear without globs of goop from someone adding green stuff antifreeze, I'm happy. The transmission fluid I like to see changed often. You're hinting that car has had that done in some way. Your car is past the 2000 models that seemed to have failures in the clip in the regulator (track) for the power windows. The cable that lifts the windows pulls out of the plastic carrier. Replaceable if you can take off the door panel yourself and send the regulator to someone on Ebay or the internet for repair and quick return for around $50-$90. I'd feel better about the car you're looking at than a Honda with an automatic transmission or air conditioning problems. Things will go wrong with all cars is my motto. Regular oil, trans fluid, and coolant changes are what your leSabre needed. Sounds like it has gotten that. You're not going to find many cars delivering 31-33 mpg in summer on interstate with AC on at 65-70 mph with 3 adults and loads of baggage; it also can carry 6 easily. It gives 22-24 around home driving in suburban township type driving here. I couldn't justify trading off my 168K 98 leSabre for a higher gas mileage car til recently. Kept the leSabre but added a Cobalt for the high schooler to drive. |
