Hey Guys,

Granted this is for a 85 Pontiac Fiero 2m4 2.5L Iron Duke, which I'm trying to get working right as it is my daily driver, but I want to learn to read the logs to start fixing my 84 2.8 carbureted Camaro.

My Fiero is running insanely rich, that much I have learned from the logs, but I can't seem to find "normal value ranges" for the readings I'm seeing in WinALDL. Here is the latest log from my drive to work this morning:

85 Fiero Data Log 11/11/2013 6:45am

I have already replaced the following on the Fiero though this is not a complete list:

Oil Pump
MAP
O2 Sensor
Air Filter
Rebuilt TPI
Plugs and Wires
Coil
Timing Gears

If someone could point me where I can find a good normal range for the values I'm seeing I would appreciate it!

*EDIT* I was getting right at 30mpg until 3 tanks ago my MPG just dropped and now I'm getting 20 ~ 23 mpg and I'm running rich, not sure what caused this.

Thanks
Grant

 

Pull codes?

could be a engine coolant sensor. when they go bad they read like it is -50deg F.

Your BLM shows it is pulling fuel. NB02 sensor shows the same. Normal is like 128 however it varies on ambient temps. I would suspect + or - 10 off 128.

 

Coolant sensor in WinALDL is showing that my cruising temp is right at 170F, so I think that's good.

 

I believe there are 2 sensors. One for the gauge and the important one for the ECU.

 

I think that one in my spreadsheet is the one for the engine because it doesn't match the one I'm getting on my gauge cluster, its off by about 15 ~ 20 degrees. Though I can go through WinALDL again and make sure something else isn't off.
