I have a 1992 buick la sabre custom 170,000 miles 3.8 6 cylinder. It was running great up until about 2 months ago it started "puttering" whenever I would start the car. Sounded like a vacuum leak, but I could not find one. Now it "putters" while the car is in motion. Mostly when I am going up a hill or sitting still at a red light, stop sign etc. Please give me some advise.
THANK YOU !
Kim
