Strange electrical problems

[jdmmatt]

Hello, brand new to forum, and s chassis's!
I have a ka-t s14 on a aem v1 ecu. if the ecu is in a weird position, the afr will read that it's leaning out. Same thing happens with the wiper stalk, when activated the car runs like shit. Any ideas if its, battery related or if I need a new harness?

Sounds like a harness/ground issue. Load test ur battery, check for draws and make sure ur grounds are clean, and bolted down tight. Battery to chassis, and motor to chassis


Btw welcome. We have a tech section or small question thread for such topics...

make sure ur grounds are clean

Disconnect the grounds, clean the wire ends and chassis with a wire brush, or wire wheel on a drill if corroded, then reconnect the grounds
