Car not running right see attached PL file??

[KCODE]

Car idles rough, INT (112), BLM (118). Seems to be backfiring while idling. O2 jumping all over the place while in idle. I loaded a PL will idling and one while making a pass or two at #20 boost. Your input would be greatly appreciated. For one I notice my TPS is not steady. Please help.

Yea looking at your files your MPH is jumping all over the place even at idle. It also looks like you drop voltage a few times. My guess would be a bad connection at the ECU.

I found one of the wires to the ECM came loose. Can I fix it or do I need to replace the wiring harness?

Did the wire and pin come out of the connector? Or is the wire broken? Either way you can fix it

I would recommend a new connector splice from caspers if the connector is damaged or has corrosion. If not you can put a new connector pin on the wire.

Okay thanks. It doesn't look damaged.
