CEL on, rough runnin after oil change


Asked by Jun 05, 2014 at 09:33 AM about the Subaru Legacy

Question type: Maintenance & Repair

My 2002 Subaru Sport has been the perfect car. Low mileage, only 29,000 miles. Took it in for an emissions test and oil change. Test passed. On the way home it started idling rough. Over next few days and several short trips totaling 50 miles, sputtering got worse, especially at starting or starting at red light or acceleration. Yesterday it backfired also. Coming home the CEL came on - steady, not blinking. The timing strongly suggests something happened at oil change or emissions test??????

Could be, how is the oil level? Maybe they overfilled or underfilled it? Since the CEL is on have the car scanned for the code or codes to pinpoint the area of concern.

There's no indication that the oil is low (check oil light not on) but I don't know if it's overfilled. How could that cause a problem? Could oil being splashed cause a problem?
