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...
