my car idles fine when not warmed up(noticed the needle is jumpy)but when warmed up it idles at around3-400rpm's and i noticed that when i get it some gas the car boggs and then when the turbo spools it gets rite up and goes!im thinking that it is related to the idle!!i have 127,000 miles on my car sp im thinking that the TB definately needs cleaning,get a new cap and rotor along with plugs,and the check for vacuum leaks!!!another thing is that i have a CEL for fuel system malfunction which i think is related to Emanage and the o2 sensors not reading right because of the Emanage not being tuned!!my o2 sensors are not even a week old but them and the highflow cat did improve response and idling some!!!i have read that if you need a vlave adjustment that it could affect idle!!!any ideas???hopefully this isnt related to close to my last thread!!!thanks for the help!!!

 

While you're doing all that...change your PCV valve. It goes un noticed and un changed alot of times and can cause this problem. Its cheap also like 2.5-5 bucks.

 

fuel managment.. end of story


i'm willing to bet that it just doesn't know what to do when it hits exactly 0 psi on the vacume system!
