ford explorer rough start up then runs fine.

[Fordtruckman01]

where would the intake manifold be located at? the one with the common leaking.

Would it be upper or lower? left or right? I do not know all that much about cars.

hey rough starter

replace the o2

 

[Fordtruckman01]

well you guys where right on the rings and gaskets on the upper air intake manifold. the rings where cracked and some I picked up played with in my hand and they broke right away. But sense they have been replaced there has not been one problem at all. I turn on the explorer and it stays on. AMAZING!! I still have one stuck o2 sensor that i have to heat up and get out but otherwise this thing is running great!!!!
Thanks for everyones help.

glad its fixed!

Good to hear that your cold starting problem is fixed! Mine is getting progressively worse as the weather cools so I've decided to order the 00M12 kit (gaskets plus front camshaft chain tensioner) today.

You'll get better responses if you start a new thread with a descriptive title in the 2006-2010 Forum.

I'm not familiar with your model but Ford usually has the #1 cylinder on the passenger side and in the front closest to the radiator. Moving aft would be 2 thru 4. #5 is on the driver side at the front and moving aft is 6 thru 8.

For the O2 sensors bank 1 sensor 1 is the pre-cat O2 sensor on the passenger side.
