Vacuum question..

ryanw · February 7th, 2012, 11:12 PM

Where are those vacuum lines going ? Check to make sure you dont have a open port on the back of the upper intake. Make sure all un used ports are blocked off. And clean the iac

ReefBlue1994 · February 7th, 2012, 11:15 PM

Will do.i changed my ECT in hopes of stopping the bad idle and surging, no
Luck. I'm also going to change my harmonic balancer because it's fried.and I've heard that improved the way it runs.

I saw your other thread, ...what does your balancer look like are you sure you didnt just mess with setting on the timming light, maybe that your issue with the balancer ?

ReefBlue1994 · February 7th, 2012, 11:43 PM

Yeah my timing is great right now but my car is all around rough and the balancer looks like its wobbling ..

Well stick with her, in 6 months she will be perfect, you just need to get to know her, so dont give up, a 19 year old car is going to have problems.

That picture you posted.....is that just a picture you found on the internet or is that your car ? Cuz the fire wall is red

Have you tried spraying carb cleaner around the intake and vacuum lines while the car is running? If there is a leak, the idle will change almost instantly. Also, if there are vacuum lines that you can't follow to their termination point, you can try pinching them off one at a time with a pair of needle nose pliers or any pliers and checking for the same change in idle. It is a great way to track down vacuum leaks quickly and easily. Just be careful around hot exhaust as carb clean is very flammable.

That goes to your EGR

But the red one need to be hooked up to the intake.

ryanw · February 8th, 2012, 11:48 PM

the other other two vacuum line get hooked up to two different valves that come off the smog pump.

It would really help if you took more then just one picture. Id like to see the smog pump and all the hoses and valves that connect to it. And the complete engine bay with all vacuum lines and vcuum tree,,, ect

We might be able to notice other things that might look wrong.

But you need to figure out how to post pictures not just the link, some of us are lazy, so you need to make it easy for us.

ReefBlue1994 · February 9th, 2012, 12:05 AM

Okay where does that red vacuum line go to on the intake?and I took off my smog pump and ran hose from pipe to pipe,like a bypass.no check engine light or anything

ryanw · February 9th, 2012, 12:42 AM

The red one goes any where you have an empty spot....normally it get hooked up to one of the small ports just like the fuel pressure regulator.

ryanw · February 9th, 2012, 12:48 AM

Do you still have your stock cats on your h-pipe, if you do, you should put your smog pump back on, with out the pump...pumping fresh air to your cats, you could clog them up.

ReefBlue1994 · February 9th, 2012, 01:10 AM

Dang...so I have to search around for where it goes?and yeah,I'll be putting on an aftermarket h pipe eoob

This port should be on the back under side of the intake. You will see that theres 3 ports on it. The big one goes to the plastic facuum tree on the drivers side fire wall. The two smaller port go to the fuel pressre reg and the other goes to the red vacuum line we were just talking about. I hope that helps

ReefBlue1994 · February 9th, 2012, 09:44 AM

Okay my red line is capped off,so I need to route that, does autozone sell vaccuum line?

ryanw · February 9th, 2012, 10:18 AM

They do but i dont think they sell that small hard style, so youll need to get a size thatslips over the kind you have.

But to tell you the truth i dont know if it will make your car run any better, im not sure if haveing all that stuff disconected really effects the car, but you can give it a sot, or wait to get some more opnions. Im in california so have to keep all that stuffT

ReefBlue1994 · February 9th, 2012, 01:30 PM

Yeah.if the red one goes to the intake do you think that would affect something?seems like it would

ryanw · February 9th, 2012, 03:03 PM

I think its just the supply vacuum for your emission equipment, since your not using the emissions equipment, then i dont think it matters. Now lets say that you hooked up that red line to the intake, but you left the other small lines, open, then you would have a vacuum leak, then i think it would effect you. So... make sure you connect the green one to your egr and the red to the intake and the other two since your not using them, cap them

Post pictures of how you ran the pipe to pipe connection when you took off your smog pump....and post the rest of the pictures i ask for.
