[DML] weird blue wires/tube things

[NJP548@xxxx]

Hey list,

While trying to get my car to run better I came across a possible 
problem that might help me. First off I have to know there are 2 different 
ECU units correct? One is called the Lambda ECU and the other is the one 
that controls the Idle Speed Regulator, right??. I took off the wood panel 
behind the drivers side and saw that there were 2 blue tube things...one was 
coming off of the Lambda ECU and the other was coming from an other unit that 
was mounted underneath the other ECU (the one that controls the Idle Speed 
Regulator) One of my questions is what do these 2 blue tube things do. And 
also I have no power going to my frequency valve and the Control Pressure 
regulator. Would that cause my car not to run right? Right now when I turn 
it on the car will rev up to about 3500-4000 RMP but then if u let go of the 
gas it will idle at around 1500-2000 RMP. But then when you put your foot 
all the way on the gas pedal again it will work its way back up to about 
3000RMP. But again if u have your foot lightly on the gas it will go up to 
about 3500RPM. At first I thought the problem was mechanical so I put a 
different Fuel Distributor on it, I got new injectors, the fuel pump is 
working so I am narrowing the problem down to something electrical so I am 
still trying to figure it out. I am also thinking it might be the Oxygen 
sensor, maybe that isn't sending a pulse to the Lambda ECU and maybe thats 
why I don't have any power going to the Frequency Valve. Could that be a 
possibility? DMC Joe does that sound right? Anyways, I am selling this car 
so I want to get it to run better for the future owner. Any and all help 
would be greatly appreciated.

Thanks a lot,
Nick
