Subject: Re: Running Problem by mseven on 2011/5/29 4:31:21 your logs show the IAC being commanded in open loop to the corresponding tables/counts v.s. temp. However once in closed loop it shows that the IAC is at 160 counts, and would be the cause of roughness and other issues you mentioned. This would mean that the throttle body blade is closed and the IAC cannot comp./add enough air. I would first remove the air horn and do a visual check of the throttle blade (to see that the blade is closed or ?) to ensure there are no issues with the IAC. More than likely you will have to re-set the min air screw so that the tb blade will be cracked open slightly(clockwise as to open the throttle blade)at idle. I would start with about 2 turns while the car is running, turn off the car and re-start so that the IAC can re-set itself. Look at the screen and keep doing the procedure until you are approx. 40 counts. |
