The 1995 Chevy Lumina comes equipped with a reliable engine, but a failing exhaust gas recirculation (EGR) valve may throw your Lumina off balance, causing rough idle, stalling and increased fuel consumption. Under proper operation, the EGR valve not only helps your engine run smoothly but also lowers emission gasses in the process. With a few simple tools you might already have in your tool box, you can change the bad valve, restore proper engine operation and keep harmful emission gasses to a minimum.

If you have a 3.1L or 3.4L engine model, the valve comes equipped with three small, rectangular boxes, about 3 or 4 inches tall, facing each other on a single mounting base. On the 3.8L engine model, the valve is a small cylinder, about 3 to 4 inches tall, with an electrical connector on top.
