Review on 🔥 ACDelco D503A Professional Ignition Coil by Bill Lacy

My 1994 Chevy S10 misfired at highway speeds in OD (4 speed automatic transmission) (misfires went away when shifting to 3rd), so i replaced my tired old original spool and i have no more misfires. Obviously this coil will fit many vehicles (which use several different mounting brackets) so be prepared to grind down the original rivet heads to reuse the factory mounting bracket. The coil came with nuts and bolts to replace the rivets and was easy to install. It can be helpful to take a picture (with your cellphone, which you never leave home without) of the alignment of the mount and coil before removing.
