Yeah the problem started before I replaced any parts. I haven't checked fuel pressure yet. I have checked and tested all my fuel injectors before reinstalling. I will check fuel pressure and o2 sensors and see what comes up. I'll post the results afterwards. Thanks everyone so far for the tips. Since owning this vehicle I've done and replaced 90% of the repairs myself. Some jobs I've done a half dozen times. This one has me a lil stumped.
