Default Problem start

I am havin a problem with my car lately. When I cold start it, it takes 3 times to get it started. When it does start, it acts like it is running on 7 cylinders. If I warm it up and drive it for a couple of minutes, then shut it off and start it again, it runs like it should.

I just had the Idle Air Control valve but this hasn't helped.

If you guys have any ideas, I would appreciate hearing them.

Thanks.

How long since its last tuneup? Check your battery to, could be low on juice.

If you leave the car sit for a while, dirt can settle at the bottom of the tank near the pumps filter. When you start the car, the dirt restricts fuel flow thru the filter and the car can run rough. If you drive for a while, the fuel stirs up the dirt and the car runs fine because the dirt isnt clogging the filter, until you leave the car sit and the dirt settles again. Its possible.

I wouldnt go messing with the tank unless its your last resort.
