Why does new furnance with propane conversion have yellow flames?


Make sure the kit included smaller sized orifice's and spring kit for the gas valve. The number on each orifice should be cross referenced with total btu's rating of the furnace. It does seem like there is too much fuel or not enough air intake (combustion air). The inches of W.C. seem fine, but you still may be getting too much volume of fuel with too large of sized orifice's. Hope that helps

Its running rich and the most likely cause is the lamba sensors ,check them out with a multimeter to check the heater circuits are functioning and the reading coming out is correct

Need 92 toyota paseo to pass CA smog test ! What causes too high HC in smog test????


High HC means moisture in the system. Try driving it longer then take it to the smog shop. Otherwise it could be hard like a head gasket or easy such as a PCV not functioning. Any ways you should always drive it about 20 miles before smog check, longer when the weather is cold.

I have a 1991 chevy pick up with a 5.7l it failed the test 2


You did not post the odometer reading on the van but base on the year it should has over 85,000+ miles on it.

The most likely source of the high Hydrocarbon (HC) is clogged or drippy injectors.

Change the fuel filter if it is over 48K miles.

Ran two or more tanks full of Chevron gas will help clean out the fuel system.

====

The air fuel ratio can be off is the air filter is clogged or the mass air flow sensor give incorrect data to the computer (ECU).

Change the air filter is it over 20,000 miles or you can see sunlight though it.

Use CRC Mass Air Flow cleaner or electronic part clean to gently clean the mass air flow sensor.

==========

Change the oil to 20W50 or one grade higher to prevent blow by.

You current motor oil is soak with HC from blow by.

=======

Make sure the tires are at 32 psi

=======

Do the smog test is a COLD morning?

=======

REMOVE excess cargo off the van.

=======

These are little things that I would do.

If the HC is still high at 25 mph then you will need a professional fuel injector cleaning or replace the injectors.


Please post more data on the third smog test on the comment window.
