Engine Troubles.

[DMCVegas@xxxx]

Ok, I just got my new Control Pressure Regulator installed. 
Accelleration has improved. But it still as good as it's supposed to 
be. The car still jerks a little durring accelleration. This will now 
appear durring both light and hard accelleration. Low speed crusing 
(10-20mph) has greatly improved. No more hard bucks or jerks. But 
when I hit a hill, the engine sputters a bit.

Since the installation of the new CPR, my car is back to almost dying 
when dropping RPMs rapidly. The best way to describe the performance 
now would be 'groggy'. She's trying to wake up, but isn't quite up to 
par yet. When I started the engine with the new CPR, it did cough a 
bit.

Now, here's the kicker. I recently picked up a used Ignition ECU off 
eBay. I swapped ECU's, and while it may just be my imagination, the 
accelleration did improve a bit more. What I did notice for sure was 
that the engine stopped "gagging" when the RPMs rapidly dropped, and 
the battery light stopped flashing.

Now, the only parts of my ignition system that have not yet been 
replaced are the Ignition Coil, Ballast Resistors, and the coil 
inside of the distributor. My LAMBDA probe is also original. The 
clock just hit 30K a while back, and the lamp is on. Even so, my 
mixture has been so out of whack that I'm sure even a new probe would 
have been wasted. So that too will be replaced next paycheck.

What is old though are my vaccum lines. The rubber is hard, and 
just 'snaps' onto the connectors. My my mode switch 'hisses'. So I'm 
a bit concerned about vaccum leaks. Another thing is when I slam the 
gas pedal, the accelleration is ok. But if I push it down all the way 
to trip the microswitch, the acelleration becomes instant. So this is 
another thing that I'm curious about. All signs seem to point to a 
vaccum leak somewhere.

If someone has some quick pointers on how to inspect/replace the 
lines, let me know. Will I be able to reach the water valve with my 
hands? I can change the distributor cap w/o removing anything, but I 
not sure If I can reach these lines. If it helps, I have a manual 
transmission.

Thanks!
