Question about 2001 Buick LeSabre

2 Answers

My 2001 Buick La Sabre custom is difficult to start, then idles roughly then stalls. This stalling occurs when I'm driving on surface streets. Did not stall on the freeway going 55mph. Wouldn't maintain idle speed on surface streets and when accellerating.

    Thanks for the feedback. How would fuel pressure effect the car in this way? How would I check the fuel pressure on my own? What is usually the fix for this if fuel pressure is the problem? Again, I appreciate your feedback.HRH.

    difficult to go uphill sometimes, poor acceleration then the engine light starts blinking. When this stops, the engine light stops blinking and goes off. This can also occur on flat road surfaces.as well.

Sounds like you a loose 12V connection at the relay box.Locate the relay box and when the engine is running wriggle the wiring harness or shake the relay bow and see if that's when the engine stalls. You may even have a bad / loose ground to the relays.
