Would like to thank everyone on this site for their contibutions it has made my life so much easier. My question is as follow
I have an Explorer-XLT, 99, 4.0, 50k miles. Early in the morning the weather is about 40 degrees it takes a considerable amout of time for my vehicle to stay running I have to maintain 2k rpm's for it to stay on. This has been going on for awhile a few days ago my engine lite came on, had Auto Zone check it on their computer and got a code reading of PO 172 & PO 174 for OBD-II. I was told by the Auto zone people it was related to the O2 sensors going bad if so which ones there are 4 of them and expensive to replace. The Hayes manual show these codes to be System adaptive fuel too rich (Bank 1 & 2) and too lean (Bank 2) After reading a few of the threads is it right to say that it's related to leaking intake manifold "O" ring seals and not the O2 sensors. Can I buy this OOM12 kit online. Thank You all.
