Hunting idle issue - ZR-1 Net Registry Forums

MuRCieLaGo · 11-10-2017

Hello guys,

Today is a good day. Been searching for a long time for my low RPM bucking issues (especially when warm).

Changed o2 sensors, fuel filter, fuel pumps, spark plugs, spark plug wires, cam sensor, battery... All without success.

Today, I changed the coil packs. It seems to have fixed the problem. The car was running fine at high RPM, I still don't understand!

Anyway, it brought a new problem. I've got slightly high and hunting idle now. As you can see in the video, nobody touched the gas pedal on throttle cable and it went all the way from 800 RPM to 1,900 RPM all of a sudden.

I've got no clue what it could be.

Any ideas?

Thanks!
