My car was sitting for about 1 a week and a half because my starter went bad. I finally changed the starter and it turned on with no problems and then quickly shut off. It takes about 2 to 3 times to get the car going. When the car finally starts it shoots out a cloud of blue smoke and then stays on. When im driving and come to a stop I notice the rpm is lower then usually and sometimes jumps up and down. People say my timing is off but dont know how that can be possible or is it. Remember all I did was change the starter. Any one know why my car would be acting up after I put a new starter. Any advice would be great. Thanks!
