Buick Lesabre engine misfiring when hot
Buick Lesabre engine misfiring when hot
when my 1989 buick lesabre gets warmed up it starts to miss really bad what cud be my problem?
Re: engine misfiring
Usually a faulty ignition component is to blame when the problem only acts up after the vehicle is warmed up. It could be a bad spark plug, or ignition wire, or coil, or module. Possibly even a bad fuel injector, as the resistance in them changes as temperature rises.
Your best bet would be to get the car scanned and see if any codes are stored in the computer and go from there. Otherwise, you'll have to get the car hot, and when it's acting up you'll have to figure out which cylinders are misfiring and then start checking components related to those specific cylinders.

1999 buick lesabre wont start
1999 buick le sabre how do you know if you have a bad cam sensor or crank sensor, car wont start.
Re: 1999 buick lesabre wont start
you would have to see if you have spark and injector pulse. Without a lab scope or scanner the way you can tell if you have a cam and crank signal is to check to see if you have spark to the spark plugs or the injector pulse to the fuel injector.
