Ok here's my problem. I installed my NX Wet kit a few weeks ago. I started of with the 75 shot and worked my way up to the 150 shot. My problem is after I use it the car really, really loads up bad. But if I shut it off and let it sit for a bit and start it back up it runs perfect. It also works if I run it in Open Loop.
Is it messing with the O2's? Has anyone else had this problem?

 

Nobody has this problem?
