well since i installed my headers.. other than some lil probs that came up.. the one that i dont know what it might be is when my idles goes up & down.. ill be driving & let go of the gas i my revs go from... 500 to 1.1k :/ i already found the culprits for the other probs (Misfires & crappy mpg) but this one is still in the air (maybe even literally, sensor wise haha) since i cant find the cause..
what can i do to fix this :/

thanks :th_thumbsup-wink:
 


I would guess Vac leak of some sort, probably not a big one bug any vac leak is bad. Gets some carb cleaner and start spraying all the vac lines while the car is running, when your RPMS drop you also find your vac leak.
 
theres a lil line..short one, cant be really specific since i cant really remember whats around it..it looks dried up.. but i never actually took it into consideration :O its located right on top of the S/C i think it goes into a T or something like that..ill take a look today & post it up with details..if its just that (hopefully).. where can i get it? thanks..

replaced vac line, it was totally dried up. replaced it & it still goes down but way way way less than before. before it was like 1k rpms now its just 100 - 200 rpms at the most. you can barely notice it but its still there, way better than before :D
