[quote=”WoodyBing” post=107987]Forget my last post, read more and sounds like a bad idea.
Would an exhaust leak before the first 02 sensor cause it to have off readings on my odb tool?[/quote]
The exhaust leak acts as a vacuum leak which fools the o2 back to the

to get a little smoke will aid in the leak finding with the rag on the
exhaust outlet.
