So I have read lots of blogs, but nothing really seems to be a possibility for my tank. I recently did a massive amount of work. Changed lifters, oil pump, oil pan gasket and "O" ring for oil pump screen/ line, water pump, knock sensors, all four O2 sensors. Used new gaskets on everything that was "Opened up". Used de-greasers and cleaners on block, heads, and intake manifold. Had a small head gasket leak along with bad lifters and not sure what else. New gaskets on everything. New OEM PCV hose, OEM fuel pressure regulator tube, New engine temp sensor. The only thing I did not put new bolts on was the exhaust manifolds. Any bad bolt was replaced. Had to remove two broken bolts from drivers side and replaced those with new bolts. New manifold gaskets. Like I said, A LOT!!! After all that, it is now missing after a brief warm up. It chugs and bogs down a lot until it gets really warmed up to the normal 190-200 temp and then only "Misses" when going up inclines or just starting out. When on flat level ground like a freeway, no issues. What am I missing???? REALLY frustrated. Cannot figure out what is needing to be replaced??? HELP. Suggestions??????
