Top 10 check-engine-light car repairs

No. 9 car repair: Replace exhaust gas recirculation valve and clean ports

Average repair cost: $325.95

Costs for exhaust gas recirculation, or EGR, repairs are up only slightly from the previous year -- by just 1.5 percent.

The purpose of this system is to control emissions and help your car run more efficiently, so cars with an EGR problem can experience rough idling as well as engine hesitation and misfires. The result can be compromised performance, reduced fuel economy and problems passing emissions tests associated with car registration.
