Re: bubblies?

The exhaust leak would have to be upstream of the O2 sensor to make you run rich.

Re: bubblies?

so it would be before the o2 sensor @ the point where headers meet heads , right? and since theres only one o2 sensor . an exhaust leak on the other header would not affect it right? or worng ?
