tgowen Posted March 17, 2012 Report Share Posted March 17, 2012 I have a 95 seville sts with some issues. i tried to install a cold air intake and when i did the engine sounded great, but started to smoke really bad. i put the oem breather box back on and it quit completely. What else do i need to do to be able to use the intake. I was able to install the maf sensor and the one vacuum line that was on the oem box. with the oem box im getting a rough idle. the filter may be a little dirty so ill try to change the filter. any other suggestions. How do i fix the rough idle and how can i use my imtake. Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted March 17, 2012 Report Share Posted March 17, 2012 What kind of cold air intake is it? Did you also get any trouble codes? Bruce 2023 Cadillac CT4-V Blackwing Follow me on: Twitter Instagram Youtube Link to comment Share on other sites More sharing options...
Abdul Littleton Posted July 23, 2012 Report Share Posted July 23, 2012 Are there any legitimate cold air intake systems for this year STS? Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted July 23, 2012 Report Share Posted July 23, 2012 In my experiments with the Northstar, more air did not lead to quicker acceleration.

Alex Caoile Posted December 27, 2013 Report Share Posted December 27, 2013 i just recently installed a CAI and loving it i feel as though throttle is a little more responsive and your rough idle might be the throttle body needing adjustment mine was having rough idle first start up of the day but after a few minutes it went away but i tried messing with throttle body and went away all together Link to comment Share on other sites More sharing options...
Z15 Posted December 28, 2013 Report Share Posted December 28, 2013 Cold air intakes and high-performance filters are good for improving full-pedal engine power. Practically that means that you are buying a modification that helps you pass (at full-pedal) or race. The key that is typically missing in the mind of the average consumer is that the only time power is increased is when the engine is at Wide Open Throttle (WOT). For those who don't know what that means, WOT is basically when the gas pedal is pressed all the way to the floor. Mike Synthoil Supply Link to comment Share on other sites More sharing options...
Cadillac Jim Posted December 28, 2013 Report Share Posted December 28, 2013 I practically never run my car WOT. It seems that there are control issues at lower speeds, and safety issues if you run WOT for any length of time. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.
