2003 Saturn Vue 4-cyl Manual Transmission 204k miles
 
Hey there,

I have a '03 Vue that is having some sort of issue with a rough idle and power loss for a for a period before a restart and then no issues. During the issue the SES light consistently flashes. This is the second time it has happened, and there has been approximately 500 miles with no sign of issues and incredibly smooth. This problem did not exist before the exhaust system was replaced less than 2 wks ago.

Within the last year the following repairs/upgrades have been made:
Ignition Coil
All Spark Plugs
Catalytic Converter
02 Sensors
Exhaust System (Less than 2 wks old)

Any thoughts or suggestions would be helpful

Check codes. What codes are set.

Flashing SES usually indicates some type of fuel burn issue that will destroy the cat converter.

Hi!

Thanks for your response- I went to AutoZone to use the free OBDII to get a general code check (despite no solid SES light and no flashing) and it spit out the random engine misfire and ignition coil code. Will not be driving it unless an emergency and on Monday am taking it to an auto-shop to get a more detailed code as well. If it is confirmed it is the ignition coil, a little disappointing considering it's only three months old, and the previous one worked almost flawlessly with very little of the spark plugs left. Any other suggestions to check it are welcome!

Thanks

With this many miles, I suspect you may have timing chain issue on the horizon. One item you might consider is an upgrade to the timing chain tensioner.

What does "very little of spark plugs left" mean? Flashing engine light means excessive misfiring with unburned fuel entering the catcon. Left this way, the catcon can destroy itself in less than 50 miles of driving with the flashing engine light.

With a well worn engine, did you try a compression test? Borrowing a compression gauge from Autozone or Advance Auto may help with diagnosing this. Autozone has free readings just by visiting them.
