1g running lean at idle and under boost

[bradcurtis15]

My wide band is reading 15-17afr at idle.. and it will die sometimes also at idle.. I swapped my chipped ECU with a stock 90 ECU and it is still running lean. I also changed the fuel pump with a walbro 255. I did a boost leak test and found that i have a leaky injector #1, I can hear and smell fuel coming out during the test. Also the maf is not hacked and still has both honeycombs. What would cause this too still lean out?? Any help is appreciated thanks...

I wanted to re post with a different topic name, its not the ECU so i wanted to state i am leaning out at idle and under boost.

You said your problem in your first post. Get new injector seals, fix that leak and let us know how it runs after that.

Okay, i was going to go ahead and replace it anyways. I was just wondering if it would make it run lean. Thanks for the help.

Yeah, it would defintely cause it to run lean. Have you noticed if any fuel is leaking out of that injector while the car's running?
