You replaced the engine head and replaced the catalytic converter. Why do you think the air pump for emission control must be plugged?. . . I have an 82 Plymouth Reliant w/ 2.2 engine. I replaced the head and now must plug up the air pump.
Has anyone blocked off the outlets for the pump??? . . . .
I had to get a replacement cat converter last year.Looks like there were two conservers required. Am disabled and unable to get down on the ground to look underneath. But I did drive the car home from the shop that installed a replacement universal cAt converter. I only have one cat. . . . .
Do you mean 2 catalytic converters? The car was originally built with only 1 catalytic converter.. . . Looks like there were two conservers required. . . . .
