Default Some help please!!!

Mycar is 2 stage75 dry then delayed 100 wet well when the wet kicked in the car poped and boged down the track. Started to miss real bad.I put new plugs in itand it helped the miss but ow it surges.
Its surging at mid rpms like you can hold the pedal at 2500 its goes up and and down between 2500 and 3000 and it idles lower than normal. I just replaced the tps thinkin that was the problem. the only code it is throwing is a random mult cyl misfires. I also putnew 02 in it also. Im stuck n e help welcomed!!!!!!!!!!!!

Try posting in the Nitrous section. My guess is fueling. Sounds like it's lean; as if she's not getting fuel for some reason (or sparatic fuel) when it goes to wet. Don't take my word for it. The guys in Nitrous oxide will be able to help you.

You might have got an intake backfire. Check your MAF for wire damage.
Also, I would clean my TB.
