I have a 2007 BMW 750li when I first start it after its been sitting for a while or first start up in the morning it runs rough then after bout 10 seconds it runs quiet
Do you get a check engine light? Is it only in the morning or after the the car has been sitting for a while any time of the day? how many miles on the car and where are you located (general area)
SOURCE: 1985 Corvette, starts runs rough then dies
I have a 85 coupe,the pumps are notorous for going out.Best bet is empty the whole tank.the pump .Is easy to pull its under the filler door.1 make sure its not your security system shutting off
your injectors .2 turn key in on poss and open gas door you should hear the motor.If not
disconnect batt and remove.be car e you dont lose the screen.once out dry off and hook up to any batt to check.there only 30 bucks but make sure you ground it out right and dont turn it on in a dry tank ,you will burn it out.
