Idle problems

Asked by Jan 14, 2015 at 09:03 PM about the 2002 Buick LeSabre

Question type: Maintenance & Repair

I have a 2002 Buick LeSabre custom, we have replaced the MFG, fuel filter, the MAF and the car still idles rough. We are wondering if it is a vacuum leak or if it could be something else. Any suggestions?
Thank you!
