I had my 2002 buick lesabre tuned-up last Friday. Today, it took 2 times to start the car. When I filled up with gas, it wouldn't start the first time and then on the second time, it sounded like a back fire and then started, but idles very rough and at times there is a whistling noice from back of engine.

    Have shop that did the work recheck it and see if they accidently cracked a porcelain on one of the plugs, crossed a wire, left something loose, etc. The noise at back of engine sounds like may be a vacuum leak. They may have unhooked something for access and forgot to reattach.
