Godzilla34 Posted November 29, 2018 Report Share Posted November 29, 2018 Hey guys Im running a Link4 G plus For some reason my s15 sr20det stalls straight after starting it. Was running mint and suddely happended out of nowhere. Few attempts later i get an fault code, 17 which is " AN V3 at GND" (Map sensor) Contacted Link techicnal support and they pretty much tried to find the problem thru teamviewer with my laptop plugged in, They deleted the error code but the problem is still there. The car keeps stalling. Any ideas on what it could be? I've tried adjusting the idle control screw and no luck. Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 29, 2018 Report Share Posted November 29, 2018 Can you give us a picture of the screw you adjusted? When I was on teamviewer with you it only needed 0.5% throttle to bring the idle right so it should be doable. Since you have no idle valve connected there is nothing else we can adjust.

The throttle stop screw is on the throttle body near the throttle cable. It will usually have a little locknut on it and either a hex socket (allen key) or screwdriver slot for adjustment.

Adamw Posted December 4, 2018 Report Share Posted December 4, 2018 If you still cant get it to maintain an idle by adjusting the throttle stop then it suggests something more major has changed, I didnt see anything obvious in terms of ECU when I logged in the other night. So it could be something like a vacuum leak or the CAS has shifted or the fuel pressure has changed etc. You really need to get a tuner involved now to narrow down some of the possibilities. If you want to do a short log of it running Im happy to take a look at it to see if there are any other clues. here is how to do a log: https://www.youtube.com/watch?v=_P1LRANeO4A Quote Link to comment Share on other sites More sharing options...
BrianC13 Posted July 26, 2023 Report Share Posted July 26, 2023 @Adamw i get a reading of .39 volts on my throttle body will adjusting the stop screw allow me to sit at .45? i see when i open the throttle body a slight bit it allows me to go past .39v. Also is there anything that would need to be calibrated through the ecu for that? when i press the gas too fast or let go fast the car wants to die it is on a base map. This is for a link g4x.

Adamw Posted July 27, 2023 Report Share Posted July 27, 2023 You unlikely need to adjust the throttle. You will need to tune fuel, ignition, and idle control before you can expect a good idle. BrianC13 1 Quote Link to comment Share on other sites More sharing options...
