I changed out intake manifold gaskets upper and lower
After putting it all back together it idled fine and accellerates fine but under steady load maintaining a steady speed it surges pretty bad. The trouble code I'm getting is 1345 engine po174 and po175. Stft b2s2 & b1s2 lean 99.2%

You have a vacuum leak somewhere. Go over your work and check all lines
