>at least the Japanese usually fix a problem when they find one.
I think you're on the wrong tact here. Do you mean transmissions like in Hondas? I can give you the link to the Odyssey discussion specifically on transmission failures. Or the Accords? Or Civics? Maybe we could talk about brakes wearing out early and often on the rears of same brand.
Or the shifting and vibration problems with the 6,4,3 VCM Accords. Some of them are bad. They have to use a radio sound to try to cancel out the noise. I don't have that problem in my 3800 in my full-sized Buicks.
or talk about the Camry with the transmission software and design problem of their 2007 transmission in their V6s. They designed the shift controls inadequately and finally compensated by varying the software. The 4-cyl also had problems of some kind. People are still asking about the patch for the programming. Then there are the rattles. This is supposed to be the car that is the example for the US cars in a few people's minds. But there have been problems through Lexus, Avalon, and Camry with transmission and engine adaptation. Do some searches here on Edmunds. I believe brake wear at low mileage has also been meantioned.
It pays to read the threads for the cars set out as examples--usually they aren't. One difference is that they have had more money to throw at problems out of profits than GM has had because of GM's high labor and management costs. That has hurt GM attempting to leave behind problematic 80s and 90s vehicles.
#138 of 305 93 Lesabre Stalls!

93 lasabre stalls when stopping but starts right back up...what could be causing this?

Lots of possibilities. One that comes to mind immediately is a defective solenoid on the lockup torque converter. Another is a defective fuel pump or a clogged fuel filter. When it's running, does it idle and accelerate smoothly, or does it jerk or stutter?

I agree with these possibilities.
He could try putting the car in neutral when coming to a stop where it's most likely to stall and see if that avoids the stall.
It also can be a weak fuel pump.
It can be a crankshaft position sensor, but those usually give trouble at other times as well.
It might be a MAF sensor. Those are easy to clean with a spray for MAF sensors or air intake cleaning. The little wires collect dirt. But those wires break easily. I spray and then touch the wires with the hairs of a camel hair artists brush.
I very likely could be a sticking EGR valve. The connector at the EGR valve could be disconnected when it's likely to be stalling and see if that avoids the stall. The EGR could be sticking on adding EGR gases to the intake causing the stall. By the time the car is cranked the vibration has edged the EGR closed like it should be. Those took can be removed and cleaned, but don't get liquid cleaner up into the area where the control motors are.

The problem im having with my car is, the check engine light come on and off. when it on the car rides ruff.when it off it will ride fine for a while then it will cut off. someone told me it was the catlic converter, but that was taken off. what could it be?
#142 of 305 2001 Buick LaSabre spark plugs
Jul 20, 2009 (10:31 am)
I just went out and bought new spark plugs and wires to put on for $100.00. I have put $4,000.00 into my car this month and like it perfect. I replace all bulbs and do some work on it so I figured I could do this. I have no idea where to start. Do you think I can do it? I am a 57 year old women who does get takin to the cleaners at the dealership all the time. I need to know what to pull. Thank you. Sandyi

#144 of 305 2000 LeSabre Runs Rough Highway Speeds
Aug 08, 2009 (5:21 pm)
Hello all. Have a 2000 LeSabre Custom with 65K miles. Owned vehicle since new. Highway cruising at a steady 55 MPH steady speed, then accelerate to 70MPH, the engine bucks a bit, but will smooth out after a short time. No check engine light, no pending codes, fuel economy has decreased about 5 MPG. Now the replacement list; Intake Manifold, TPS, Plugs, Wires, Coils, EGR valve, Oxygen Sensor, Fuel Filter, Air Filter, MAP sensor, and Catalytic Converter (it was bad - the elements were loose). Cleaned MAF, cleaned Injectors (while Intake was being replaced). Checked fuel pressure; idle 45 PSI, idle with regulator hose off, 55 PSI, accelerating to 3500 RPM, 55 PSI. Compression check; all cylinders between 200 and 210 PSI - compression builds quickly. Engine oil changed at 3K mile intervals (Mobil 1 10W30) and drinks 1/2 quart between changes. Any ideas? Wish the PCM/ECM would give me a hint. Perhaps ignition module? Knock sensor? Please help me save a few bucks here and get this old ride back in shape. Thank you.

Sounds typical of wires or plugs. Your wires could be up to 10 years old, if the car were built in 1999. So that should be the first change. Use AC plugs and used AC wires or Belden OEM quality wires.
You might check the wires with a grounded screwdriver moved over them while running to see if you attract a leaking spark. But I'd just replace the mess of them for $40 or so at NAPA with AAA discount or AC/Delco wires at other volume suppliers.
