Car runs good in cold weather, when temperatures get to be in the 70s and above, sputtering and near stalling situations occur. Changed egr valve last year, thought I nailed it.. Wrong!
1993 Pontiac Bonneville 270,000 mi,
Im having the same issue where the upper egr tube goes to the upper manifold. Its a newer astic manifold and cant find a replacement tube. I definitely have a leake there confirmed by the smoke and water test.
