Guys, i have an s14 sr in a s14 chassis. i had an idle problem, it was jumpy and i would bog out sometimes. First i tried adjusting my ide by disconnectings the TPS and messing with the idle controller..that didnt work, my idle would jump from 1200 to like 900 back and forth. When i connect the TPS, the idle settles to like 800-900 but when its night (colder air) the idle dips down real low...600 or so, but thoughout my daily driving, day or night, my idle jumps around still.
So i changed my fuel filter (300zx) my fuel lines (i used a slightly larger diameter 7mm instead of 6mm cus autozone didnt have any)
I changed my boost and vacuum lines (i was using 1/4 before and im now using 7/32)
I didnt use any hose clamps on vacuum or boost line (from the manual boost controller to intercooler)
the lines fit nice and snug and i dont think i have any leaks on the new hoses.
I have a oil catch tank recirc. back into the intake, i have a manual boost controller, stock intercooler and piping, stock mafs...
Now heres the problem im having now. The idle is still a little jumpy but much better..it does rev to about 1200 at times then sometimes it sits at 900 or so but it doesnt jump too much, it kinda just revs to 1200..
When im driving, i can hear the turbo spooling but when i give it more throttle, it just feels like the boost isnt kicking in at all, and i cant hear my turbo as much. i also get a slight ticking noise sometimes and it sounds like its comming from my injector side.
Right before i changed all the hoses, i didnt have the boost problem. i was boosting 14psi and i dont have a boost guage (i had the car tuned with afc and they set the boost for me.)
oh, and i have a blitz bov and its kinda old but seems to be working fine.
ANY HELP would be greatly appreciated, thanks in advance.
