Be careful... O2 sensors in open collectors can be exposed to a backwash of air, causing the engine to run very rich.

Re: oh god its loud

yeah i noticed, i filled up and im already down to 3/4 tank in 30 miles
and at idle it acts like its about to choke out
but i sure as **** fixed the lean condition! now it just dumps gas out the pipes
think i should for the time being mock up some autozone pipe with some clamps for drive-abilities sake?

For the sake of your sanity and others around you, your engine's well being and your gas budget, put an exhaust system on it.

Re: oh god its loud

posting under this thread because i think it might be related
the car when cold bogs and wont hold idle (have to double foot it) but once warm its fine
i noticed the little tube that comes off the intake elbow and goes down was putting tension on the water pump sensor harness
could i have fouled my o2's from running open headers, or am i looking at a stretched out terminal or broken wire in that harness?

Re: oh god its loud

okay nevermind
started it up with the maf unplugged so it'd default to its speed density tables and it ran like a dream

Re: oh god its loud

where are you located? I have a few different exhaust systems here in NY including an offroad Y pipe for long tube headers.
