need help asap! car idles like crap

[giovanniv]

Alright so I have been having this problem after I installed my 1g 7 bolt into my 97 gsx. I start up the car and it idles very rough to the point where I have to push on the gas very slightly to keep the car running. I did a boost leak test and my throttle body had leaky shaft seals so I replaced the throttle body and now there are no leaks. I also thought that my front o2 sensor was bad because of the crazy reading that it was giving so I replaced it and still didn't make things better. Here are the 2 logs that I got from last night.

Terry's Talon Troubleshooting Tips #3 - Fast Idle (aka. Idle Surge) There you go this should help.

But it is not only my idle... well atleast I don't think it is. My wideband reads basically fully lean and my idle surge wouldn't explain my crazy o2 sensor reading.

EDIT ahh just read some of the link. so you are saying my idle is so sparatic because of my lean a/f ratio? I guess that makes sense but now I need to find out why I am running lean.

UPDATE

Got another log today. Unplugged the maf while running and I could tell a difference so I guess the maf is working? I'm getting spark in every cylinder also. Fuel pressure is at 44. My exhaust also makes a sort of popping noise because its running lean?? My base timing is dead on at 5degrees BTDC. I am stumped!

FINALLY!!!

Car is fixed! I am so relieved that I finally found the problem! After searching for days and days I found it! It turned out that when I had wired in my aem wideband, I spliced the 76 input instead of the 75th! Well the 76th input was for the front o2 sensor and NOT the rear o2 sensor! What a noob mistake! Well I wanted to post up the links that helped me find my problem for anyone in the future who runs into this because I know for a fact it will happen to someone else.

This is the thread where I found the answer in post #8.

The FrontO2 reading in that log is pegged high. By looking at RawFrO2Volts (instead of FrontO2 which is clipped in software to 1.1v), it seems like you've may have a wideband's 0-5v analog output connected to the front O2 input instead of the stock O2 sensor or the wideband's simulated narrowband output.


Here is the pinout diagrapms that I used that matthewdesigns gave me on dsmtuners
