Today it was messing up so i pull in my driveway and unplug the O2 sensor and then drive it with it unplugged. With it unplugged it messed up just like it did when it was plugged in. Does this mean bad O2 sensor?

what exactly do you mean by messing up?

Irukandji · 12-30-2005, 10:15 PM

messing up = CEL?

If so, Read ECU codes

1500-2500 it bucks.. and 4500- redline studders and just makes you not wanna go above those rpms. My friend told me it sounded like a V8 striat piped.

not necessarily, my blacktop didnt have a CEL with my bad o2 sensor. Only reason i knew my o2 was bad was cuz I got a Apex'i pen turbo timer and it wasnt reading the o2. thats how i knew it was bad.

i thought sr 02 sensors on came into play at idle.

The fuel system doesn't use the 02 Sensor when at idle, or until it reaches operating temp. and at WOT.
