Upping my low idle???

[E30_Aza]

I'm wondering if there's a way to up my idle? I have a 2.7 with a 288/288 Schrick cam (not my choice) it idles crap! At around 400rpm. Feels like it will konk out. Is there anyway of upping the idle? It also has one of speed touches chips in, whether that makes a difference I don't know. Any help will be appreciated
Cheers

you can make adjustments at the throttle body but with that cam, you really need to get it mapped properly.

Thought that might be the case. Doh!!!

speak to Ant also low idle is not necessarily a problem unless it stalls.

Idle really should be 650/750rpm,although with an aftermarket cam it may need to be higher still.

Idle can be adjusted at the throttle stop screw on the top of the throttle body...but...adjusting this will mean that the throttle position switch(TPS)will also require adjustment.Failing to adjust the TPS will mean that the engine will run rich at idle as the ECU thinks that the throttle is open.

So I would start by inserting a feeler gauge between the throttle stop and the throttle arm to obtain a higher idle without losing the base position.Then remove the t/b and re-set the TPS to suit this position,reassemble and see if it now idles as required,if so,remove your feeler gauge and adjust the stop screw to the new position,this should be locked in with thread lock.

Nice on buddy. I will be giving this a go in the mean time. I will be getting it remapped at some point but money is an issue as usual. Thanks for you help guys

YOU CANNOT MAKE ADJUSTMENTS AT THE THROTTLE BODY!
There's a small plug hanging off the engine loom near the ECU. The black/purple wire in this plug is provided to increase idle speed when the aircon. on so equipped cars is turned on.
Applying ignition switched 12 volts to this pin should increase idle speed.

Ok Brian, do you know roughly what it increases by? How much rpm
