A common problem on the later-model Chevrolet Lumina is the failure of the Exhaust Gas Recirculation (EGR) system. This is due to clogged passages in the intake manifold and it affects all engines of the Lumina, not just the 3.1-liter one. Also reported is that the lower intake manifold gaskets, tend to wear out quickly. When You change out Your manifold gaskets use a stronger gasket than it came with.A faulty EGR valve can cause problems with the flow and operation of the EGR system leading to performance issues including a power reduction, reduced acceleration, and decreased fuel efficiency. EGR valves can become stuck 'open' or 'closed' due to a build-up of soot particles, carbon deposits, and dirt from fuel.

The most common chevy lumina problems are related to the engine leaking oil, and the transmission shifting poorly.

The most common problem is not the EGR alone. The cooling system is made with low grade metals that over time crack. The radiator on the exit side cracks. Unfortunately the Lumina engine cooling system over all is definitely a big problem especially with the top of line LTZ with the 3800 V6.

We've discovered with our 99 lumina LTZ, 3800.V6. The cooling system has numerous expensive repairs. The parts are low grade plastic not metal. The radiator has cracking issues in the exit side. The major issue is the intake (large black unit on top of the block).
