Question about 1993 Saturn SW2

1 Answer

Car stalls intermittantly without warning

1993 Saturn SW2 just shuts off - doesn't matter if the car has been running an hour or 5 minutes or the outside air temp or conditions. Sometimes it starts right up, and sometimes won't start up for hours.

Try pulling the engine coolant temp sensor, They often crack not sure why but the ceramic tip cracks makes the car hard to start, the car's idle may race while shifting gears, and often smokes. The sensor is on the right side of the engine when looking at it on the head. Easy to change and get too

My 02 Saturn sl2 will run fie then dies like vapor lock(no fuel). I changed egr,plugs wires fuel filter and scanner says codep1599 ?! I'm at a loss, without going from bumper to bumper


without going from bumper to bumper ????? You need to see what's missing after it dies , spark or fuel pressure . Don't guess ,test an if you don't know how ,take it to a qualified repair shop. Your fixated with vapor lock . Crank sensor , ignition module .

DTC P1599 will set if the PCM has detected an engine stall condition when:
• The engine is in run mode.
• The ignition voltage is present on circuit 439.
• The crankshaft position (CKP) pulses at the PCM are NOT detected.
DTC P1599 is a type D DTC.
The powertrain control module (PCM) has the ability to set a diagnostic trouble code (DTC) if the engine stalls when the ignition has not been turned OFF. This DTC may aid in intermittent diagnosis of a customer complaint of intermittent engine stall. The scan tool Failure Record information can be duplicated under the same stall conditions in an attempt to reproduce the occurrence. Since DTC P1599 is a type D DTC, the PCM will not command the malfunction indicator lamp (MIL) or SERVICE telltale On. This DTC can set due to driver error. For example, a vehicle equipped with a manual transaxle in which the clutch was released too quickly causing the engine to stall, will set DTC P1599.

Car stalls out after its warmed up .ive replaced egr valve ,idle control,temp sensor


Do this service.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Car starts and runs. Once it's warmed up, the engine shuts off tried to start it again motor turns over but will not start. Wait a couple of hours then the motor will start again and then will shut off...


Wouldn't think sensor or computer problem , more likely an ignition module . When it dies pull a plug wire an check for spark ,i think you will find no spark . Just from my 30 years of diagnosing GM vehicle's this has been the #1 cause of a start an run till warm an dies an wait 20 min . to an hour an it starts again problem. But without testing to know for sure that would be a guess . Having a qualified an certified repair technician diagnose the problem is always the best idea.

1999 Saturn SW2. High coolant temp and transaxle warning light comes on intermittant. Auto trans. Runs and sounds fine. Any idea of the cause/cure?


check the tranny fluid. if it's dark brown it and the filter should be changed. they can do this at most oil change places. but it could be as simple as some loose sensor wires. hope this helps.
don't forget to add 50% water and coolant to your resevoir tank of your coolant when it's low.

1998 Saturn SW2, 180,000+ miles. Recent starting problem.


It does sound like an electrical issue.  Double check if the ground connections are all OK.  You may have to check out the wirings, even the wiring loom if all wires are still OK.
