Before the law was revised in 1990, it was only illegal for professional
mechanics to remove or disconnect emission control devices. There was
nothing to prevent a motorist from tampering with their own vehicles. That
loophole has since been plugged.

THINGS NOT TO DO

Any of the following may be considered emissions tampering and get you into
trouble:

a.. Removing the EGR valve or plugging its vacuum lines
b.. Removing or disconnecting the PCV valve
c.. Removing the stock air cleaner and heat riser duct plumbing
d.. Removing the catalytic converter
e.. Removing or disconnecting the air pump
f.. Removing or modifying the stock distributor vacuum advance/retard
g.. Altering the stock ignition advance mechanism or timing curve
h.. Replacing the stock distributor with an aftermarket unit that is not
emissions certified
i.. Modifying, removing or replacing the stock computer or PROM chip with
a non-certified component
j.. Blocking the heat riser duct under the intake manifold
k.. Knocking out the filler restrictor on the fuel tank inlet pipe
l.. Replacing the stock non-vented gas cap with a vented cap
m.. Removing or disconnecting the fuel vapor recovery canister
n.. Changing the idle mixture or stock carburetor jetting
o.. Removing or modifying the carburetor choke
p.. Modifying or replacing the carburetor accelerator pump with
non-certified components
q.. Installing an intake manifold or racing manifold that lacks provisions
for the stock EGR valve and/or a heat riser duct
r.. Installing a carburetor that lacks the stock emission hookups
s.. Installing non-certified fuel injectors
t.. Installing a long duration "racing" cam that is not
emissions-certified
u.. Installing exhaust headers that lack provisions for a heat riser
valve, an air cleaner preheat stove or fittings for an oxygen sensor (if
required)
v.. Installing valve covers with open breathers or no fittings for a PCV
valve
w.. Installing any induction, fuel or ignition system component that is
NOT emissions legal
