My idle is rock-steady before and after the Moroso catch can installation.

 

Lol cool cause it did the same thing even when I put the stock tube back on. And the idle only does this on mine after the car has been driven for a period of time and really warmed up. Thanks for getting back to me.

 

Man I thought I was a perfectionist noticing everything. Man you have me beat!!

No worries Been traveling.

 

I dont have the oil separator but I have that idle problem and many more do. Why it does it I do not know.

 

Lol the only reason I noticed is because I read of someone having a vacuum issue after an oil seperator install. I had that in my head after my seperator install and caused me to notice the idle change. I guess it makes me feel better other people experience this as well.


I would really like to know why it does this!

 

The idle changes on our cars because idle is now mostly controlled by ignition timing. That said the computer is constantly advancing then retarding the ignition timing, even at idle. This is done to keep the NOX down. This is what causes the RPM to swing up and down.

 

Nope, I pay close attention when idling after warm up. My focus developed a an idle that would jump around a bit after a year on the road. I tried several things to fix it. Including cleaning the MAF sensor. Nothing fixed it. Then one day it started getting really bad, apparently the ECM was on its last legs. A new one was ordered, but the same issue persisted. I never did find out what was causing it, but I assume one of the sensors was dirty causing it to fluctuate. Car ran fine. but in the Focus' the ECM tended to go bad sometimes. Luckily I caught it right before the bumper to bumper warranty ended and had found a place (Tousley Ford) that sold them for $200.00 if it should happen to again (it was an easy replacement as it was built into the throttle body).

My mustang currently idles at 650rpm rock steady once it is warmed up and in gear. Before warm up and in park it will jump around a bit.

 

If you unhooked the battery to do the install, might try an idle relearn.

 

If you review a data log of our cars while they are runing, even at idle the idle is constantly moving, and the timing is continuously changing. That's how the computer controls idle. It advnaces the timing then retards teh timing, continuously.

 

2014Gt what data logger do you use?

 

Your SCT tuning tool will data log and you can use the free SCT data logging software right from their website to analyze.

 

I put the stock hose back on for some warranty work and after driving it for a few days I noticed the idle stays constant with the stock hose on. So that obviously tells me there was some sort of vacuum leak with the steeda part installed. It's strange because I made sure everything was tight when I had it installed! After a few weeks of driving when I had the steeda separator installed I noticed barely any oil in the can anyways so I guess the stock hose will say on for now.

 

Nope. If anything I've noticed that the idle has smoothed out. It would jump around a little bit during idle with A/C off, and it doesn't do that anymore.

 

I'm all for Steeda but I sent back their separator when I realized that you had to cut the stock hose to install it. You have no back up and your car is deadlined if something goes wrong. I went JLT for that reason. After 3 years, the jlt fitting cracked at the hose and I had my stock hose to use until my new one came in.

 

Steeda provides the hose with their kit. I wasn't happy with my first attempt at cutting the hose so I ended up cutting into the stock hose which ended up fitting decently on the second attempt. I went ahead and purchased another stock hose from the dealer for backup. It would be nice if steeda included the hose precut cause their is barely any room for error. Measure twice, cut once! Wish I took my own advice lol I think there is some sort of vacuum leak with the steeda kit installed so I have the stock hose on for now.

 

Ok so I'm probably crazy but I noticed the idle doing the same thing with the stock hose on. Looks like I'll be putting the steeda seperator back on.

 

SONICBOOST,

Looks like all is well ... if you ever need anything ... you can reach me at tim@steeda.com!

The oil is based on how you drive ... the more aggressive you are ... the more oil you may see.

I have the Steeda and love it. I custom made a hose and have no issues. I just installed the track key and this car is an animal. If there was a vacuum leak I am sure it would be throwing a code? I noticed on the Steeda and a few others that if the can is not tight with the o ring not getting crimp what you described will happen.

 

Mine came with the hose. It was a Ford factory replacement hose.
