Just checked my car for that hose but couldn't really see much, looks like a hose or two runs underneath the coolant resevoir, and they appear linked to either PCV and/or brake booster but I could be wrong.

Can't get pics ATM but that hose is definitely suspect! And if that's your brake booster hose, well there's your problem lol!

 

Pretty sure it's just an overflow tank. It's number 15 in the picture above.

OK so just to make it easier on everyone here is a list of everything I have tried with the outcome of each test:

1. Checked W/M check valve - clean, still having misfire problems.
2. Completely disconnected the W/M kit - still having misfire problems.
3. Switched Coilpacks around - still have misfire problems on same cylinders. Did not follow coilpacks.
4. Pulled and tested the ICM's - both are good (according to the test) and still have misfire problems.
5. Swapped ICM's - still misfiring on same cylinders
6. Swapped spark plugs around to see if misfires follow them - no go, misfires still on same cylinders as before.
7. Replaced all the spark plugs with new ones - still having misfires on same cylinders
8. Pressure test - could not find anything leaking. Still having misfires.
9. Visually inspected all all the vac lines - could not find anything. Still misfires.

I am pretty sure thats it.

Here is my list of what I am going to try again today when I get off work:

1. Disconnect the wire from the MAP sensor that goes to the W/M kit and see what happens.
2. Compression Test (If this fails I will be ROYALLY PISSED!!!!!)
3. Spray down the engine with soapy water and re-try the pressure test.
4. Check all fuses that have to do with fueling... I will probably check them all anyways.
5. Throw a freaking wrench.
6. Have it towed to a buddies shop and see if a fresh set of eyes can find anything.

If anyone has any other ideas of stuff for me to try please please please LMK. I am getting desperate.

That hose is just for overflow that you pictured. You may have burned some internals or something, you checked all the little things, I'm starting to believe its something big. How about the timing, what about the camshaft, crankshaft sensors?

EDIT!!! HOW could I have not seen this! Check the INJECTORS! It only makes sense.

 

How do i go about checking the injectors?

Oh and I am thinking that they might be giving to much fuel since the plugs are wet and not dry. So it's obviously getting fuel.

BUMP FOR PROBLEM FOUND! Not so good.

See first post.

If you have 0 compression, you have to have a bad valve or few. Yes, you could of had a timing belt slip or strech that could of caused it. Auditech79 would have a better list of causes than me, he does own one also. Dont know if he is in this thread yet or not, but he needs to be

 

I don't think he is. I will PM him. Man this sucks BAD!!!!! I haven't even put my real license plates on the car yet!

Ok, Here are some logs I took. I am wondering if the controller for the W/M kit was bad. Look at how low the RPMs are when the IAT start to drop. I think the kit was injecting way before I built boost up. Possibly it was injecting as soon as I went to WOT?



Any input?

What's your mileage on your car and when was your timing belt last changed?

Woops edit, just reread the first post.

If your up to pulling the engine, do that. It should make it a little easier to work. Though, if you can tackle it with the engine in, go for it.

Called up the company who made the kit?
