I finally finished installing the new ZZP coupler and putting the SC back together. In the proccess i have broken all the fuel/air lines that were possible to break and just now put them all back together. At first the engine would work for about 15 sec and DIE but it was nothing serious, just couple of ait lines that I forget to connect.
Now i am having more serious problem and to be exact my Water Pupm became a Water Gun/Sprayer. At first it runs normal but then the engine starts to stall and WP starts to spray collant all over the engine and while doing that the engine acts all funny, it stalls to the point when it almost dies but then the RPM go up again and it starts to work normal but after about 10 sec same thing happens again.

I know that there is a problem whit the WP i just wonder why the engine acts so funny.
Any ideas?

P.*.
The only good thing is that there is no more annoying rattling!!!

First off, ensure that all the vacuume lines are hooked back up properly (there should be a diagram under the hood). It is not uncommon after having the SC off to have a rough running engine for the first bit. You really need to get the waterpump fixed first. After that you can keep the engine running by manually operating the throttle until it "relearns" how to run.

Just took the car for a spin and for some reason the boost will pn;y got til the middle (zero) i am suspecting the cause is a faulty belt which probably slips, but so far the engine is still very rough and acceleration is slugish.

The evidence definetly points at a common problem between the SC and WP. Belt, most likely. But spraying water? Did you take the WP off?

nope haven't touched the water pump.

Try rechecking the bolts on the SC. If they have loosend up and air is leaking thru there will definetly be performance issues. I do also agree to get the WP fixed just to get that out of the way.

one more small detail, i have noticed that on the climate control the temperature reading is constantly blinking, you hae any ideas what that means?
