Alright guys, my car sputters only on a warm start. I have a h/c package on my car. About a month ago, It was raining hard as hell and the next day my rear 02 sensors went out on me b/c they got wet. I went on to replace them and figured I nwouldn't have to worry about it. Now, on a warm start, my car acts like it is not getting any gas. It starts it after about 30 seconds of driving and the car must sit for about 15 minutes. It will only do it once as well. I can push the thottle and it does nothing, just sitting there like it's about to die as I go rolling down the road. Once I pump the throttle a few times all the way down to the floor, it's fine again.

Also, it feels like it loses alot of power when this happens. But once I drive it around for 10-15 minutes or so, it's fine. On the same note, I was out racing the other nite and after about 5 hard races, it seemed to lose power.

WTF is going on? Thanks in advance!

Also, a good friend of mine (whom is my tuner, Alex Procter) went out with me the other day to look at what the car was doing with HPTUNERS. He said that it all looked fine to him. BTW, this guy definately knows what he's doing.
