What engine???
The 1997 S10 Blazer has an egr (Exhaust Gas Reclaimer) valve. It also does not have a point distributor, it is electronic.
It is behind the throttle body, on the intake manifold.
Check your EGR valve Check EGR valve
Clean EGR valve, maybe stuck open with carbon
Plugged fuel/air filter? Plugged catalytic converter? Engine timing? Check EGR Valve
how do you replace dome light in s10 chey blazer?
If you want to locate a new egr valve, check with your local auto parts store. If you want to know where the egr valve is located on your vehicle, post the year and engine size of your S10.
2003 4.3's do not have an egr valve.
There is no EGR valve on the 2002 4.3L (code W)
The Exhaust Gas Recirculation Valve on a 1989 S10 is located in the valve cover. It is toward the front of the motor.
It depends if it is a 4.3 or the 2.2 engine but, in general the EGR valve is located on the intake manifold.
Idle Air Control Valve
