My new air filter seemed to help some. About 1-2 more mpg. I had an exhaust manifold to downpipe leak. I fixed that last week and waiting to see results. From past experience when resetting the ecu it takes a hundred miles to adjust some trim values. I only have a couple more things on list that could be possible. My new o2 sensor doesn't work as it should. I have a partial blockage at intake manifold. Clogged injectors which is doubtful. I still have a vacuum leak somewhere that i cant seem to find. This is doubtful too.. I think it could be a combination of things and ill know when i get around to taking manifold off and cleaning it thoroughly. Got to get my ac system working first.
