My dad's been busy so I haven't been able to get the hood up on it. It's not doing it now that it's dry out, so It's gonna be electrical. I'm going to check the TB as soon as i can by using a spray bottle, and make sure my 02's didn't come loose. But I do have a band clamp just behind the headers holding the y pipe together from when It had to be cut off, so the water i went thru may have just leaking in and gotten on the 02's.

That's my plan as soon as i get a laptop.

Went thru some water again this morning and it started cutting out again real bad. No light this time. Checked 02's and they are tight, wires are all in good. Soon as it dries it runs fine.

Probably just have to deal with it until I get a laptop purchased. Then wait for some rain and see if i can get it to miss again to see if it throws a code.

Well. It started missing again when i got close to home today. Didn't hit any water this time. I've got some household repairs that need to be addressed so i might go get a 6k loan tomorrow if it's worth it.
Go ahead and do the house repairs and get a laptop for my efi live and have a bigger stall, 4.10s and a locker put in.
That should take care of the miss and the loss down low from the cam install.

I can't figure out wth is wrong.

Plugs are new. Fuel pump made noise when I got it but hasn't recently. I can check the wires on it to make sure it's not a bad connection on the sending unit. If that checks out I'll have to get a gauge and check the pressure.

It's just really hard to do this stuff when my bro's a lazy bitch and my dad's always at work. I can't even get the hood up by myself.

Okay. So it's still doing it. Went thru a water hole today on my way to work and it immediately started cutting out. I'll plug my laptop in when I get home but the engine light did not come on.
I really doubt water is getting sucked back up my Y-pip where there is a leak but it's possible. It almost seems like it's getting in my fuel line, so i'll check the fuel filter.
The only wiring that I can see is the one for the rear O2 sensors. A dog got ahold of the passenger side one and ripped it up. so I'ts hanging there with bare spots.

Any other suggestions?

Still sounds like something electrical to me, wether it's an open wire in a harness or an ignition issue. Did you swap plugs and wires yet?
