T Series Ignition Coil P/N:DR31T
Standard Motor Products
The T Series DR37T ignition coil for the 1988-1995 Chevrolet C1500 4.3L / 5.0L / 5.7L and other vehicles is an electronic coil that steps up battery voltage so the spark plugs can fire.
A weak coil can show up as a misfire, rough idle or hard starting. Before you replace this coil, rule out worn spark plugs, damaged plug wiring and a loose connector, since each can produce a misfire on its own.
Vehicles it fits include the 1988-1995 Chevrolet K1500 4.3L / 5.0L / 5.7L and the 1994-1995 Chevrolet Impala 5.7L, and each takes one coil. If your car isn't named here, open the "Vehicles it fits" section and look up your exact model and engine.
