Hey guys my 1992 5.0 threw a code 44 which is air injection or air injection inoperative.But the check engine light will come on and go off. I do believe that the reason it does that is because the computer fixed the problem or i might be wrong. I have recently replace all the vacuum lines under the hood about 2 weeks ago because i got a code 33 no egr flow. So fixed that now this came up today.I have also put on anew smog pump when i did the motor rebuild since the old one was seized up that was about 5,000 miles ago. Is anyone else having these problems or know what it might be? I have no clue where to start at.

Thanks

Nicholas
