Re: 2000 Cadillac DeVille: Blinking Engine Light/ Hesitation and Rough Idle- Help
As has been the case for me for a while, my wife steals my car to go to work because she likes it better than her van. Then I get a call that its acting up. Oil was low, filled it up. Check engine has been on for a while but now it was blinking. It has a kind of hesitation on take off almost like a sputter as if something isn't hitting right. Idle is rough as well. I'm usually working on this stuff myself but I usually send code issues to the shop. We are kind of broke now due to having a car we are trying to sell in the shop so I need this done asap and as cheap as possible. Any guidance on where I should look to get started?

you WILL have a P0300 code - amongst others -
P0300 is a generic misfire code -
our on-board code readers will not display WHICH cylinder/cylinders is/are misfiring -
only that there IS a misfire -
take the car to any large auto parts store - they will check your codes for free -
P0301 is a misfire in cylinder #1 - P0302 is cylinder #2 - P0303 is #3 - etc -
once you discover WHICH cylinder is misfiring - diagnosis becomes much easier -
