Hey guys I am having a surging idle issue with my car and can't seem to find the problem. I had the original f22a1 intake on it and it surged after I did my boost setup. I changed to a h23 intake on this install and it is still surging. I can't seem to get it to stop the wawawawa 1200rpm thing, this also causes it to be jerky in normal low speed/low rpm driving. I know when I turn my key over the fuel pump never turns off, if I were to just turn the key to the on position and not start the pump would run until the battery died...

It didn't do this when I first put the Walbro 255lph pump in, could this be the cause of my surging idle problem? Why does my fuel pump not stop priming?

read this and preach it like ur bible !

 

and what would you say if I told you I did all of this on my old intake and the same symptoms are present with this one? Not being smart *** by any means, hope it doesn't sound like I am. I am just trying to get to the bottom of this.

 

If your fuel pump is not turning off, your main relay is getting stuck or it thinks the car is running. I doubt that is the problem of your surging idle though since too much fuel will simply return to the tank. Does it surge all the time or just when warm? Bleed your coolant and check for vacuum leaks.

 

Can't find any vacuum leaks and have bled the coolant 3 times .
