I need to top the oil off. What I need to do since I am getting two codes, One for it running too lean and the other for EGR failed flow, is change the EGR, clean out the intake, take down the exhaust, rod the cats, beat them, get them cleaned out, then re-install everything. I was thinking of getting the stock exhaust manifolds ported. A lot of people have done it and ceramic coated them as well and say that after getting them ported, it was better than a set of JBA headers. Dunno how true that would be, but never hurts to try.
I don't plan on having to change anything again (unless it's a routine maintenance kind of thing) so I am going to make this a bullet proof car, redo the engine as much as possible on my income and when funds permit, drop a 4v Romeo in her :D.
