I have 1999, S80 T6
I change my alternator and right after my car hesitate to start every morning.
I had cylinder 6 firing up before the alternator change, but starting was normal.
Then on day, my car didn't start. I towed it the following day and once at the mechanic, it started normally.
I killed the battery trying to start it. I changed the cylinder 6 and all the spark plugs. That was a partial tune up.
That should have made my car run smoother. No at all, the check engine came back a couple of days later.
The car's rpm fluctuates. I still feel the stalling. Most importantly, It hesitate to start. I have to press the gas for it to start.
Also, right after my alternator was changed, I get the battery signal. I press the gas or once it's warm, it goes off.
I notice that if I start my car with the door open, it comes up more often.
I am a woman and I am not sure if I am taking advantage of
I appreciate your feedback and replies
