Guys,
Mate has a 200 sx t plate but its an auto. Hunting badly on idle.
No EML on and no fault codes showing. Just wondering if anyone has seen this before if its something common.
Cheers
Ian

boost pressure test needed, clean AFM too
Meant to say this vehicle is totally standard no mods. Where do the wing mounts usually crack? Is it usually visible from a quick look?
Cheers
AFM cleaned and swapped wing mount with known good (my old one) still the same.
Struggling now
Pressure test the intake, it could well be a leak still.
still most likely cause is a boost leak - although with the WMIC out of the equation its less likely.
Idle control?
has he got the aircon on, as it tends to drop the revs (n.b. if you have air to windscreen only its automatically got aircon switched on)
unplug your lambda sensor see if it gets better, just had same problem and new lambda sorted it. Mine did it when warm
AC not on. Is idles speed adjustable on these?? Although it does run quite rough, how can i pressure test the intake system?
Also checked spark and compression on vehicle just to be safe and all ok. Are the plastic pipes bad for cracking anywhere??
I had similar last week, turned out I hadn't tightened the boost pipe to the turbo after changing my manifold
oops! Not good. Nah still nowhere with this one. Gonna start swapping all sorts from my own to try. Swapped all boost pipes with my old ones to rule them out. Really struggling now.
Ruled out:
Boost hose
Intercooler
O2 Sensor
Cleaned AF meter
Ignition coils and AFM ruled out as they have been pulled off known good one
Just driven it for the first time and noticed the brake pedal is solid!!
Servo issue? They bad for seals or anything???
Where is the PCV valve on these engines? Is it down behind the inlet manifold??
erm...... is there a hole in the vac pipe to the brake servo?? seeing as you have a rock hard brake pedal. that would make it hunt
Have tried blocking that off and it still hunts. Tried a whole can of wd40 all over the place and cant seem to detect it. How can i pressure test the intake system? Is it better to vacuum it??
Sticky EGR Valve was the problem. Blocked off and runs like a sweetie. Done it ages ago but forgot to add on this in case anybody gets the same issue again
I thought that S14a's didn't have an EGR valve?
Yeah they do mate at the rear of the head
