installed a mishimoto oil catch can yesterday and now at idle the rpm's drop like its going to stall then they recover to about 900rpm and repeat about 20-30 seconds between each drop..im running summits ss braided lines to it bc the lines that came with the catch can colapsed under vacum. im not really sure what the problom could be, all of my connections are tight and im positive i do not have a vacum leak. has anyone else have this happen to them? i was thinking about doing the peddle reset to the tb but i heard its a PITA. thinking about just taking it off and selling it.

thanks guys

 

anyone?

 

got it for bling factor? is there any need for catch can with no fi?

 

yes, bling factor

 

i would give the gas pedal reset a go first, the regular reset, not for the TB. and if that doesnt work, do the tb reset via pedals.

 

ok ill try it. thanks..if it dont work this thing is coming off.

 

lol yeah, who needs bling anyway

 

there is acctually oil in it so it must be doing something lol

 

this happened to me found out that there was a hole in one of my hoses.

 

i dont think the ss braided hosed could colaps on the inside can they. and i know i dont have a hole.

 

woops sorry OP didn't notice that u have SS hoses. Shouldn't unless something pierce the hell out of them

 

double check all the connections and make sure there isn't a vacuum leak somewhere

 

I had the same thing happen when i installed the Greddy can.Go get some carb cleaner spray and spray it around your connections and ill bet you will find a vacumn leak.The rpms will change when you find the leak.

 

^ +1. I had a vaccuum leak coming from the transparent hose to check the oil level on my catch can. I'd check there first.

A catch can is good to have regardless if you have FI or not, it'll still catch the oil vapors.

 

fixed it..i just relized i took my ztube off the same day and for got to put the clip back on the vacum line to the ztube i feel dumb.
