SOURCE: The windows in the 95 oldsmobile cutlass ciera won't work at all

maybe the wire is severed where the door (drver dr) pivots. thats what was wrong with mine. there is a rubber boot with crinkles in it that hold all the wires together. you can also try replacing the switch board that controls the wndws on the drvr dr. hope that helps.

Since your cat was replaced you should be looking at fuel problems...even gas cap seal....check fuel pressure,fuel regulator,and evap system.>canister or purge solinoid,o2 senser...high nox is caused by the cat or fuel problems on these engines...high pressure in the combustion chamber...lean condition>air leak on hoses,or high compression caused by carbon build up ...there is no EGR on this car so don't waste time looking for it...hope this points you to your problem

Failed hc ppm& feul evap test


If I read your post right, you are over on Hc and that is all? Check the air filter, check the injectors. You are either not getting enough air or are getting too much fuel.

Emission test failed HC (PPM)


i can be, only 2 things, or both.
1: engine running way too rich.
2: dead cat.
(both happens, too)
replace the cat, might be cheaper that full engine diagnosis and repair.
in a real shop we test the cat. using up and down stream tests.
with the 5 gas analyser.
but the truth is a new CAT can hide a very filthy running motor.

It is possible that you need to replace your catalytic converter. If your converter is bad it will cause you to fail an emissions test every time.

A good fuel system cleaning and tune up will probably have you sailing through inspection. RE Cal state laws, you need to contact DOT (that law changes daily)

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.
