1985 Corvette misfires
I changed out coil, cap, rotor and Delco wires. New R 43 TS plugs. Car runs worse after changing out parts? notice two plugs insulators are glazed and white remaining plus have a reddish tint to them. I am suspecting two injectors are stuck open.
Do I have to pull the intake runners to get the injectors out?

it should run better!
firing order 18436572.
Sometimes while changing plug wires, you can get the 5 and 7 mixed up....

thanks to all who responded. Firing order with regards to plugs wires is correct. I have two spark plugs whose insulators are bright white and glazed I'm thinking I have two injectors stuck open? dumping gas into cylinder plus the snorkel is ripped. I'll replace snorkel and dump some Sea Foam into vacuum port of brake booster while running and see if I can get the two injectors to work properly.
