Question about 2000 Saturn Ls 4dr Sedan
I tried to rule out all the obvious first. I replaced the fuel filter and will possibly consider the fuel pump. For a vehicle having 105k miles on it, it is too young to retire or trade in. Taking it to a Saturn dealer is like opening your wallet to a crack addicted mugger, so I am compelled to work through a solution. After I fix this I have to tackle the changing of the "timing belt" before it breaks and ruins the head. The idea of a timing belt over a chain makes no sense at all, except for the dealer who asks you to shell out over $1000 to change it.
The stalling happens frequently. There is no common occurance such as accelerating, decellerating, braking or idling. No service light has shown yet. I have read that AutoZone will read a code for free, thus avoiding the painfull gouging of $89 for the dealer will charge for this 30 second task.
As for the stalling, any suggestions will help.This is my wifes car and she is driving my full size truck until I fix this.
The problem may be caused by a faulty fuel pump. I've replaced a hundred of these ('98-'02 S-Series fuel pumps) if I've replaced one, for this exact condition. You will only notice the sluggish-ness on hot days. If you will have the fuel pump replaced you will most likely no longer have these problems. Your fuel pump has a little plunger inside of it (the actual part that pumps the fuel). On most of these Saturn's, on a hot day, the plunger will expand with the heat. The sleeve that this plunger rides in does not expand. Hence, you get a plunger that will not move freely inside its sleeve. Hope this helps. I would probably tell you to have the fuel pressure tested and monitored while the condition is happening. If you've only got 10-20 PSI while driving, you've probably found your problem.

The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
