I have a 93 4.0 and it has no EGR valve. My neighbor who is a Ford mech. says some don't have EGR's and some have only one O2 sensor.
on the backside of the engine
Need more info. Which valve are you referring too?
On the 4.0 L OHV engine, the EGR valve is located on the driver's side of the engine. how do i repair it
On the throttle body
The knock sensor for the 1993 Chevy Cavalier is located in the back of the motor. It can also be located in the engine valve.
The electric fuel pump is inside the gas tank
1993 what?
As I recall, that engine does not have an EGR valve.
Near the firewall behind the engine, or under the dash near the heater core.
all you have to do is pull it off. it should be located on the top of your engine. i just changed it in mine,
