I have an 87 with the 4.2 . I have a strange thing going on with my power steering . I had it in at my buddys shop and asked him to check out my power steering since he was already fine tuning my carb/timing . To my suprise he said it was working fine . (it wasnt when I dropped it off) . a week later it quit again .. now a week after that its working again (who knows for how long) is this just my Pump going bad or ??? .. any suggestions ?
