Hey guys,
About a month ago I replaced the cylinder head, gasket, etc in a 2.7. Immediately after the repair it ran totally normal. A week or so later it idled a little rough, but nothing serious. It got a little worse running, but still nothing too serious. I chalked it up to mabe a bad batch of gas or something. A couple days ago I drove it to the mountains and back and now it runs awful: no power at all, sounds/feels like it's misfiring, yet it's not. It's basically useless under 3k RPMs. Also, there are no codes at all in OBD.
What are the odds that it's as simple as a clogged catalytic converter? When the head gasket went, it of course dumped a bunch of coolant into it, and it's also the original with 250k miles on it.
