would an exhaust leak cause lean or rich sensor reading?

Re: would an exhaust leak cause lean or rich sensor reading?
I concur.
It is was rare that I could get my YJ to start and actually stay on
the fast idle cam and fast idle until warm, but with the HEI ignition
I can actually do this about 50% to 60% of the time now. Generally I
have to pump it twice and feather the gas for about 30 seconds until
the engine wants to idle, then I flick on that sol-vac switch I
installed and hold the idle at 1200 rpm until it warms up.

Re: would an exhaust leak cause lean or rich sensor reading?
I do like that sol vac trick. I have a manual choke and need to monitor
it for the first 30 seconds or so depending on how cold it is.

LOL, okay maybe I'll just live with it and do a manual choke mod when
next winter rolls around. Thing is it runs perfectly smooth for 7 or 8
seconds and then takes a nose dive to stumbling before slowly getting to
the fast idle setting.

I think I've got the same "heater" in my YJ, crack the window for a
smoke and and icicles form on the output ducts. Fortunately the winters
been pretty tame in VA this year, though they're never anything like up
in the great white north.

LOL, okay maybe I'll just live with it and do a manual choke mod when
next winter rolls around. Thing is it runs perfectly smooth for 7 or 8
seconds and then takes a nose dive to stumbling before slowly getting to
the fast idle setting.

Mine used to work like that in the fall and summer. It was plain crap
in the real cold.

Yup, you have the same heater.
You can fix it's case easy! A blower motor from a full sized 73 Blazer
4x4, 350, auto with AC fits right in. The hole under the battery needs
to be cut bigger, but the squirrel cage fits right on.
http://www.off-road.com/jeep/tech/body/heater.html
Some place in the US sells two versions of the motor for some reason.
Labeled wrong is my thought. One is longer shafted. You want the short
one if they have 2 choices.
It is a wicked upgrade! Literally low is better than the stock high was
for volume. You can defrost all the windows, even in the real cold.
