If the CAT is hollow the O2 sensor does'nt heat
up enough.
I passed emissions today-only after I put a good
CAT in.
I also replaced three leaking injectors. They
were leaking slowly after the engine was off.
Catalytic converters get hot- Oxygen sensors work
best when hot.
other tips:
Change the oil-somehow this lowers the HC.
Have the idle up around 850-950.
Drive about 100 miles with premium gas and the
timing retarded slightly. I put Seafoam in the
gas and oil.
check to make sure valves are at 0 lash.
plug wires all good, cap, rotor.
idle /full throttle switch properly adjusted.
Coolant temp sensor tested
I also put a bottle of some stuff that claims
"guaranteed to pass emissions."
It's the second time using it helped me pass in
two different cars.
it cost $8.00 a bottle- it should.
So doing this and more took me from 431 ppm HC at
idle to a passing 131. Cruise was 99.
