my check engine light tells me that i need an egr valve, if i install one will that cut the light off????
depends if nothing else with the emission system is messed up
Possibly. If you don't go out then you need to have someone hook up a code reader and clear the SES light.
Possibly, unless it's a Ford. A lot of the time on a Ford, it's the DPFE sensor that sets an egr code. Or do you mean ther is no egr valve on the car? Some GM and Chrysler engines were built with and without egr valves, (2.2 GM, 3.3 Chrysler). If someone replace the engine, you will need to get the parts required for installing an egr valve. In the case of the 2.2, it means a different cylinder head and exhaust manifold, the Chrysler 3.3, a different intake and rear exhaust manifold.
