The 1991 Geo Metro EGR valve can be located on the air cleaner housing. The valve will be on the back of the housing.
It is inside the air intake with the air filter.
Were can I buy a throttle cable for a 97 geo metro
no adjustment possible
i dont think so.
do you mean the PCV valve? the PCV valve is located in the intake manifold
No, it will not. After 1994 the Geo Metro became more curved so any part from before 1995 will not fit your geo metro. You can use any hood from 1995 - 1999 depending on the body style.
do you mean the EGR valve? it's at the base of the intake manifold
