I replced the clutch and now 1st and 2nd seem to be reversed car takes off fine in second but sluggish in 1st bogs down when you switch from 1st to 2nd

It was bogging out if you would step in it real quick. I replaced maf sensor for that and it doesn't bog anymore but I was getting engine light replaced gas cap it went awa y then the light again this time the O2 sensor. What's next fuel pressure regulator? I had the throttle body and injectors cleaned out with the pressurized solvent. New plugs and plug wires. New battery optima. Any ideas seems like hard to diagnose
