Default My car is running like sh*t!

A few weeks ago I took my car to the car wash and washed off the motor. I have done this plenty of times before and never had a problem. This was the first time I did it with my FAST. As soon as I left I knew I had a problem. The car acted like it had no power then all of the sudden it would come alive. Also my wide-band is showing be running lean mid 13s.

I though that maybe I had cracked a plug and it wasn't burning the fuel/oxygen. So that would be why it would cut out on power and my wide-band was showing it running rich. So I changed the plugs but it didn't change anything.

I was at Theblurls1's house one day when he pointed out that I didn't change the valley cover bolts and I may have crack my intake ( it didn't have instruction, oops). So I pulled the intake yesterday to find no crack thats a good thing. So I put it back on and go for a drive.

At idle the air/fuel is 16.0 which is the max reading set on my WB. When cruising rpms above 1200 its at 14.8. But when I go WOT its like the power enrichment table aren't kicking in. It goings strait to the max reading 16.0 and has even lean popped. I don't know if the water messed up an injector, or what. I know its running worst after I took the intake off. Are the gaskets reusable?

I'm lost I bought a can of starter fluid and sprayed down each side of the intake but it never changed how the motor was running. Any ideas, I can get a video if needed.

The stock bolts are to tall and the intake hits them. I had impression in the intake where the bolts where but no crack. So I changed out the 8 bolts that touch the intake to the ones that come with it.

OHHHHHHHH you have a FAST, I see now. I should read more carefully sorry I don't have any real input I just saw that and started wondering. Did you check to see that maybe a hose got knocked loose causing a vacuum leak? I know it's far fetched but I would think that something related to the wash caused this, seeing as it was fine before it, and totally FUBAR after. Is it a power wash or a mist that you rinse the motor with? I'm somewhat unfamiliar with it.

It was around 180 temp. Right after I but my intake on and took off I remembered I left the A/C line off. I pull over fixed it but still nothing. Here is 2 videos of what it is doing.

Edit: It was the soft mist from the engine and tire cleaner.

I paid 300 for it. The initial tune was a dyno tune. Then after the Fast, Theblur fine tuned it with that a/f gauge.

From a small speed shop in beaumont. The sensor is in the driver side of the Y-pipe. All my injectors are in good and my rails are tight. I think I can here it sucking air when im in the car but can track it down.

It came with its own sensor. It works fine, something is wrong with the car. After the tune we had it dialed in at 12.8. Then in got a little lean over time so he put some more fuel on it. Then after the wash it when back up. I wonder if my fuel pump could be a factor?
