GT2860r now fitted, but wont run properly!!

Fitted new above turbo 2day with standard s15 actuator..
Run's perfectly, but when left to tick over car WILL NOT rev..:(
You put your foot down and it the engine revs to 2000rpm then bac down to tick over, 2000rpm then bac down again etc etc..
But as soon as you cut the power, turn car off and start ignition again, it run's perfectly for maybe 10 15 min's then when left to tick over, Happens again...
It is very hard to explain but i hope somebody knows what it is..!!
Specs are
-Standard black top SR
-Induction
-Front mount
-De-Cat Back exhaust

Any info would be highly appreciated..
Thanks Conor..

He can boost a bar with a standard map on that turbo, reving it to 2k wont even bring in the boost.

jees conor , did you by any slight chance disturb anything else or forget something real simple just a thought

As far as i know.. I didn't forget anything chris, don't no what it is??
It has to be something simply, because the car drives perfectly and only on tick over when you leave for 10-15 min's, then it starts hunting..!
Would it have anything to do with the s15 actuator??:confused:

emm doubt it sure thats just a controller if ya get me ?maybe im wrong what about lamda sensors plugs etc etc ? tweak of the idle control valve no

can you put the old actuator on? i have a brand new one here ya can try if that helps. took it of the 2871r

Did you plug the o2 sensor on the elbow back in or damage the wires?

Yeah i understand.
Would lamda sensors/plugs have an effect?? Is it not jus for emissions??:confused:
Adjusting the idle control, didn't help tried a few times!

Yeah plugged it back in..
Could be possible that 1 of the wires got damaged..

tweek

sounds like unmetered air is getting in to the system i.e lines or pipework not connected properly or a leak in them.is the elephant trunk connected properly??pipework from the afm to the turbo.

sr20 afm will be grand for that turbo up to one bar.don't bother with a z32 afm for that turbo a rb25 one will be plenty big for that turbo and more than half the cost if you are going up grading

standard ecu uses the lamda sensor to adust fueling for the entire map.

double check all your vacuum lines and wiring going to afm

me too thought it was a dash light etc etc
09-11-10, 14:02
Conor sr_20

Yeah its a decat..
And don't think it does matter but when its plugged in the car is still hunting, as soon as you dis connect block connector.. Car runs perfectly!
Is it safe to jus leave it disconnected??
09-11-10, 14:41
way2fastforu

ya its safe to leave that block connecter for the cat sensor disconnected..all its there for is if the cat gets blocked or get too hot it'll bring the light up on the dash...you could take the sensor out altogther seen as you've a decat an jus block up the hole wit a bolt an bit of exhaust paste
