Idling Problem

[Owens 40828]

So why is that Tee in that vaccum line coming from the front. Should I remove it and just straight line it. Would it matter if I hooked that line up to the s on the vaccum tree. It pulls stronger than the one that is currently on the source vacuum.

This was in my vaccum line going to the back pvc restricting 99 percent of the flow. Anyone know why..

Don't know
why they t'd it, but your brake booster should have a direct vacuum source, not ported vacuum. In the old days it could be like the base of carburetor, full vacuum. Maybe one of the other guys can comment on your tee that was added. I don't own this vehicle..I couldn't tell you. Try removing the restriction, run full vacuum see what happens.

What type intake is that? Did the previous owner give you any info on the car? Do you have any basic automotive knowledge? Need a little help to help you. If you have no info on the car/motor first place to start is to get a vacuum gauge and find constant vacuum around 17 or higher at idle. That will plug into the vacuum tree. You may be able to t that source with the pcv valve. Than check you brakes, should have a better peddle, no hard. Then we can help you from there. Buy a repair manuel for your car and maybe squeez some info from the previous owner. The people here will help you best they can.

I have an entire book of records on the car. Don't know the previous owner. It's a pro m 80 intake with a truck flow intake manifold.

Trick flow intake.


Can we see more pics of the engine and various lines and maybe a shot of the vacuum tee?

Hope that helps

Can't make out too much being sideways. Really need some closeup clear pics of the vac lines and such

 

[Owens 40828]

I just found out that the tee in one of the lines was a catch can.( homemade) should I put it back on or leave it off. And just let the pvc do its work.

 

[General karthief]

A vacuum line to a catch can? Is it suck'n vacuum? If it is plug it.
I had to go back and see what your original problem was. Did you get vacuum to your booster and is it working? Sounds like previous owner was a little vacuum impaired.
Could not have been the beer though.

I think he means an oil separator.

That's why we just need more pics. We need to see what's going on there. It's a non factory config, so it's hard to guess

 

[Owens 40828]

It probably is a separator. It comes of the intake manifold to a tee in the line. Then it travels to the pvc. This picture shows it.

 

[Owens 40828]

Sorry it's upside down . But it's the 1st outlet on the left..

I did get the brake booster working alittle better than before. With this lunati cam my vaccum isn't going to be great.

 

[Owens 40828]

Ok new problem....thought my IAC was bad. Went out and got a new one. It's did t help. My car idles better with the IAC unpluged. Why

 

[stykthyn]

If you put a new iac on you need to do a base idle reset.

If you put a new iac on you need to do a base idle reset.

Did had the same outcome as the old IAC

 

[stykthyn]

Did had the same outcome as the old IAC

Then the iac wasn't your issue

 

[Owens 40828]

Then the iac wasn't your issue

This idling problem will be the death of me. It just don't make sense. It idles fine as long as the iac is unpluged. Doesn't smell rich or anything. Anyone have a ideal.
