So car runs good everything is checked that I can check and test. Now it idles fine once warm and a little rough when cold but my problem is that the ecu now does nothing. The air idle control screw works sort of but really only when it is pushed all the way in it wants to die. No vaccuum leaks or gas problems I have 2.3 approx CO. Timming is good
What else to check? |

guess im lost cause they are all new hoses and it runs great idles at 900 no problems. but as soon as i close the TB adjustment screw it it basically dies. i did just check it and it does affect it a little bit probably about 200-300 rpm up or down. so its not 0 adjustment. but the ecu does nothing. maybe 50rpms it looks like

No air=no runny. 2-300 sounds normal, the further out you go with the screw, the more you need to richen the ECU knob. Timing will affect idle a LOT as well. |
